Note: Harry Potter was created by J. K. Rowling and is a film series owned by Warner Bros.

The students of Hogwarts had an infamous reputation, due to all the antics they caused and all the rules they broke. One day, the students were singing and dancing on desks. The teacher, Severus Snape, was disgusted by his students' behavior. He stared at his students, while asking, "What's happened to you? I know you can be rather immature, but this is downright despicable. You need to sit down and start reading today's book." Hermione Granger looked eager to start reading the book. However, she was the only one. The other students started prancing around the classroom. Ronald Weasley turned on the radio and started rapping.

A few minutes later, Harry Potter entered the classroom. He sat down and looked at Professor Snape, while saying, "I'm sorry I'm late. Hagrid wanted to wish me a happy birthday and he gave me a few gifts. I felt it would be rude if I left before thanking him."

Professor Snape replied, "I suppose that was nice, but kindness doesn't excuse being late. That's something you need to learn."

Hermione raised her hand and said, "I respectfully disagree, Professor Snape. There's always time for an act of kindness, even if it means being late. Considering how much I dislike being late, you know I'm not joking around."

Professor Snape replied, "Fair enough."

Harry looked around and saw the other students goofing around, so he asked, "Why is everybody acting so silly?"

Professor Snape said, "I don't know, but a majority of this class will be receiving detentions. Now, get to work. You don't get to play around, while you're in class. In fact, you're going to be staying in my classroom, longer than usual, in order to make up for the time you wasted."

Hermione raised her hand and said, "Professor Snape, most of the students won't be able to stay. In fact, most of us won't be attending this week's classes."

Professor Snape looked annoyed and baffled, while asking, "What are you talking about?"

Hermione explained, "Harry Potter's birthday is this week and the other students and I need the week to prepare for Friday's birthday party. He's turning twenty."

Professor Snape said, "If you think you can take a week off, you all belong in Arkham Asylum. You won't be able to skip a single day."

A moment later, Professor Albus Dumbledore popped into Snape's classroom and started dancing around. Dumbledore went to the front of the class and said, "Greetings, students. Dozens of students have asked if they could take the week off, in order to prepare for Mr. Potter's birthday party."

Professor Snape whispered to Dumbledore, "Old friend, a lot of people have accused you of being a crazy old man. If you actually let the students skip a week of school, for such a petty reason, you'll make a fool of yourself."

Dumbledore confidently replied, "I know what I'm doing." Dumbledore looked at the students, while saying, "Some people claim everybody's equal, but if I must be brutally honest, that's not true. Some people are extra special and cool and Harry's one of those people. After all, he saved our school from Voldemort, so he deserves the best of birthdays. He's going to be twenty, which is a big year. Go ahead and start planning the party. Have a great time."

Ron patted Dumbledore on the back and said, "Thank you. I must admit, that I used to think you were a crazy old man. However, I realized you're the cool type of old person. You're like the wizard version of Santa Claus."

Dumbledore replied, "Thank you, Mr. Weasley."

Professor Snape walked up to Dumbledore and asked, "Are you sure you made the right decision?"

Dumbledore said, "I might be old, but I'm not crazy. Everything's going to be fine."

A short time later, Ron walked up to Hermione and said, "Harry's going to have such an awesome birthday party. Luna's working on an ice sculpture, while Neville and the others setup a dancing platform. Even though Harry will be the birthday boy, I'll be the best dancer. Where is the party going to be at?"

Hermione was surprised Ron didn't know, but considering Ron only knew three of the world's states, it wasn't that hard to believe. She said, "It's going to be outside, next to the parking lot."

Ron nervously screamed, "Oh, no!"

Hermione asked, "What's wrong?"

Ron said, "Harry's car is going to be finished being repaired, on Friday. Because of that, he's probably going to be in the parking lot, which will lead to his party getting spoiled."

Hermione replied, "Hopefully, he won't see it."

Ron responded, "I'll make sure the party doesn't get spoiled."

Hermione asked, "How?"

Ron said, "Although I'm a legendary slacker, I haven't been slacking off, when it comes to learning new magic tricks. My wand can do tons of magical things, so everything's going to be fine."

During the next few days, Hermione and her friends prepared for the party, while Ron goofed around. On Friday, Harry and Ron woke up. Ron got out of bed and said, "Harry, you should consider sleeping in."

Harry replied, "I don't feel that tired."

Ron said, "But your party's going to be long, so you should get some more rest."

Harry replied, "That's okay. My car's finished being repaired, so I'm going to get on the bus and visit the mechanic."

Ron pulled out his wand and whispered, "I know a trick, which will stop Harry from leaving." Ron pointed the wand at Harry and zapped him. Harry fell to the ground and passed out.

Ron said, "Since Harry's asleep, he won't be able to go the parking lot and see his party. However, he could wakeup, at any moment. I better make sure he's put somewhere, where he won't be able to see his party." Ron picked up Harry and started carrying him out of the room.

A few minutes later, Ron Weasley was outside, while carrying Harry. He turned around and saw Draco Malfoy, so he asked, "What are you doing?"

Draco sighed and said, "Even though Harry's not a very cool person, I figure I should be a good sport and attend the party."

Ron replied, "That's admirable of you."

Draco had a smug smile on his face, while responding, "I'm a very inspiring person."

Ron said, "I need to put Harry in a place, where he can't get to the parking lot. Otherwise, he'll find his party and everything will be ruined."

Draco wanted to be nice, but he was tempted to get revenge on Harry. He had a sinister grin on his face, while saying, "You should put him in the sewer."

Ron had a confused look on his face, while asking, "Why should I do that?"

Draco explained, "He won't be able to see the party, while in the sewer. He'd be so confused, about why he was in the sewer, that he wouldn't be trying to find the party. When the party starts, you can find him and pull him out of the sewer."

Ron said, "I don't know if Harry will enjoy sleeping in the sewer."

Draco replied, "Since he's asleep, he won't be that uncomfortable. Besides, he might find the home of the Teenage Mutant Ninja Turtles."

Ron said, "In that case, I think I'll agree to your idea." Ron opened a manhole cover and put Harry in the sewer.

Harry fell into the part of the sewer, where Voldemort had been hiding. Voldemort had an excited smile on his face, while seeing that Harry had fallen into the sewer. He walked closer to him, while saying, "Greetings, dear enemy. I don't know how you got here, but I'm glad you've arrived. Are you alive?" He tapped Harry on the head.

Harry opened his eyes. He looked around, before he realized his arch-enemy was in front of him and that he was in the sewer. He had a confused look on his face, while asking, "What's going on?"

Voldemort said, "I don't know, but I can guarantee you, that I'm going to be getting some sweet revenge. You see, my unmenacing rival, you might of defeated me, but I managed to survive. I moved to the sewer."

Harry sarcastically replied, "What an eloquent home. Are you and Oswald Cobblepot roommates?"

Voldemort said, "You shouldn't be acting like a jokester when you're around me." Voldemort pointed to his weights, while saying, "I knew you and I would cross paths, one of these days. For the past couple of years, I've been doing tons of exercises. I even joined a kickboxing club."

Harry smirked, while asking, "Did you have a boxing match with the Riddler?"

Voldemort said, "Batman references will not help you, Mr. Potter. Nothing can help you, because I'm about to bring you down."

Harry nervously said, "For what it's worth, today is my birthday."

Voldemort replied, "I remember your first day. It was supposed to be your last birthday, but your pesky parents ruined everything." He grabbed Harry, while saying, "I'm going to give you the birthday present, that I should of given you, when you were just a baby and that gift is your demise." He did an evil laugh.

Harry said, "I'm going to stop you. I defeated you, during our previous battle, so I'm confident."

Voldemort replied, "Your confidence is about to fade away, along with your existence." Harry and Voldemort started battling each other.

Harry and Voldemort used their wands to blast each other. Both wizards were confident. Harry started using some new spells, while saying, "You should give up, Voldemort. You were a threat and I was afraid of you, but times change. You're outdated. You've lost your touch."

Voldemort had a villainous smirk on his face, while replying, "You're wrong about that. During the past few months, I've been learning new tricks. I've learned several dastardly things which will lead to your downfall."

Voldemort tried to use some of his new spells, in order to get rid of Harry. However, Harry learned a protection spell, which blocked Voldemort's attacks. Harry said, "You might think you can win, but I know you're going to be the loser of this fight."

Voldemort looked amused, while asking, "You think I could be a loser? I'm so scary that most people are scared to speak my name. Meanwhile, you have one of the most common first names that anybody could ever have."

Harry replied, "My actions are better than my words."

Voldemort said, "Considering your lack of clever comebacks, I don't doubt that. However, I have my own comebacks and my newest comeback is going to lead to your end."

Harry and Voldemort continued trying to blast each other. Voldemort looked upset and impatient, while saying, "I'm sick of your protection spell. You must be using it, because you know I'm stronger than you. If you didn't have that silly thing, I would of already destroyed you."

Harry replied, "You're wrong, Voldemort. I'm a better wizard than you."

Voldemort started laughing so hard that he almost fell to the ground. He said, "Harry, I'm one of the most well-trained and powerful wizards, that any world has ever seen. Even Grindelwald's crimes are lacking in comparison to mine. You're a kid who was raised by a uncaring uncle, because your parents weren't strong enough to stop me and nobody will ever be as strong as me."

Harry replied, "You're wrong. My parents sacrificed themselves, because they knew the right people would find me and they'd teach me the necessary magic, to bring you down." Harry started using his newest and most powerful spell. Voldemort tried to use his wand to block the spell. However, it didn't work. The spell started blasting Voldemort.

Voldemort tried to remain confident, despite being in pain. He did a crazy-sounding laugh and said, "You're a fool, Harry. Your youthful energy can't compare to my wise knowledge."

Harry replied, "I'm twenty. I'm not a kid."

Voldemort said, "I'm much older than you and I know more spells."

Harry said, "You can keep bragging, but I can tell you're feeling weaker."

Voldemort tried to keep standing, but he felt so worn-out, that he felt he had to start laying on the ground. Voldemort said, "I refuse to accept the fact, that you've beaten me. One of these days, I'll eliminate you and it'll be the greatest birthday present that the wizarding world has ever received." Voldemort passed out. Harry smirked, while walking away. His birthday turned out to be a success, after all.
