Voila! All nice and spell-checked! Except for "inofficial". It's supposed to be that way.
The Inofficial Rulebook of Hogwarts: Part Two
26: Saying "I think I 'taw a puddytat!" every time you see Professor McGonagall is most certainly NOT a good idea.
27: You may not offer Albus Dumbledore one of Fred and George's Canary Clusters and tell him that it is a new kind of Lemon Drop.
28: Setting off fireworks in Professor Umbridge's office so that all the plates of sickeningly cute cats come crashing down is ALSO not a good idea.
29: You may not bring an albino rabbit to school and threaten people with "Don't make me sic the Killer Rabbit on you!"
30: Follow-up to number 25, 30!: In fact, giving any pet to Grawp is not a good idea.
31: You may not tell all the first-years that the Grecian Underworld is below the school and that if they want proof, they can go see Cerberus, who lives on the third floor corridor.
32: You may not place yourself on a stairwell and block all the students, saying, "To cross the Bridge of Death, you must first answer me these questions three!" and then proceed to flip students off the stairwell if they answer a question wrong, such as "What...is your favorite color?"
33: You may not sell Saphira to Hagrid or Ron's brother Charlie.
34: You are not allowed to give Peeves a suit of armor for Christmas.
35: Nor are you allowed to give him gum.
36: Telling the Merpeople (in Mermish) that they look ugly is not a good idea.
37: You are not allowed to march around seventh-years with a jar of dirt, saying, "I got a jar o' diirrtt, I got a jar o' diirrtt..."
38: Calling Grawp Bigfoot generally isn't a good idea.
39: Calling any giant Bigfoot REALLY isn't a good idea.
40: Charging the Whomping Willow with the Sword of Gryffindor is not allowed.
41: Replacing Voldemort's wand with a trick wand from Fred and George's shop will not amuse him.
42: Offering Voldemort a colonial-era powdered wig (complete with ponytail) will not amuse him.
43: You may not train a flock of chickens to attack on command and tell anyone who'll listen that they are Tae-Kwan-Do-Does (Do-Dos? Anyway, a bunch of Do-Do birds together)
44: Repainting the school bright pink will amuse no one except Professor Umbridge.
45: Asking a centaur for a pony ride is only going to get you an arrow in your head.
46: You may not tell the first years that a hippogriff is part hippopotamus. It isn't true.
47: Giving Voldemort one of Willy Wonka's Hair Toffees for Christmas is not going to amuse him.
48: Giving Hermione a hair straightener for Christmas might amuse her, but it'll amuse you more.
49: Asking Draco Malfoy whether or not his mother is in love with herself is not going to amuse him, his father, OR his mother. (That's what narcissism means-to be in love with yourself)
50: You're not allowed to invent Love Potion Number 9 and 1/2 during Potions.
