It was a normal summer day in Retroville. And in the lab of Jimmy Neutron: Boy Genius, which was located underneath the backyard shed by secret, Jimmy was testing out a new invention.

"Okay Goddard," Jimmy said to his robotic dog. "Let's test this out."

"Bark bark!" said Goddard.

Jimmy throws a lawn dart at a target board.

"Goddard, transport goo-dart," said Jimmy, reaching out his hand. "Hand."

Goddard licks Jimmy's hand as the dart disappeared and reappeared in his hand.

"It worked!" said Jimmy, happily. "With this Matter Transporter, I'll never have to be worrying about missing the school bus ever again! You can just beam me right into my desk!"

"Incoming message, Jimmy!" said the Vox 2000. "Incoming message!"

"It's a message from the deep of outer space," said Jimmy.

"Dissevering message," said Vox.

"This is what I've been waiting for since the day I was born," said Jimmy, looking at the screen where he receives sent messages from others. "They're never going to believe this at school, Goddard!"

Goddard hears the word "school" as he transports Jimmy at the front of Ms. Fowl's classroom at Lindbergh Elementary School. But Jimmy was still in his underpants.

"Neutron?!" said Cindy Vortex, trying not to laugh.

"Jimmy?!" said Ariana Atoms, not believing her eyes. "Where are your pants?!"

"What are you talking about?" said Jimmy, looking at himself. "AAAAAAHH!"

The class starts pointing and laughing at the undressed boy as Jimmy tries to cover himself with a textbook.

"Mr. Neutron!" said Ms. Fowl, squawking like a parrot. "Show and tell is in two days!"

Jimmy quickly ran back to his house to get dressed while feeling very embarrassed about himself being naked at school.

Later that night, Jimmy and Ariana were in the Hover Car flying up to the top of the telephone pole where the power lines were since Jimmy was going to do something.

"Jimmy, why were you naked during class?" asked Ariana.

"I forgot to get dressed while testing out a new invention, Ariana," said Jimmy.

"Oh," said Ariana. "Anyways, what have you been up to lately?"

"Well, earlier today I received a message from space," said Jimmy. "But when I got home to check it, Vox informed me that the message was erased. So I didn't get a chance to open it in my inbox or read it."

"Sorry if I'm getting off topic, Jimmy," said Ariana, looking down. "But we're pretty high up. I'm afraid we'll fall off the Hover Car and land on the concrete below."

"Don't worry, Ariana," said Jimmy. "You've been in my Hover Car before."

"I know," said Ariana. "But I've only been here in town for a few days. And I just met you. So I don't know if I should think your inventions are going to malfunction or go haywire anytime soon."

"Just don't think about it that way, okay Ariana?" said Jimmy. "Anyways, I went into Retroville's power grid. We are going to use all the lights in town to spell out a greeting to the alien life forms. Watch this."

He flips the switch as the lights spelled out "Greetings From Planet Earth!" over the houses.

"What do you think, Ariana?" asked Jimmy. "Pretty cool, huh?"

"It's very nice, Jimmy," said Ariana. "No offense, but I think this message is too simple."

"Yeah, I agree," said Jimmy, flipping the switch again. "Let's try something else."

The lights then read "We Love" with an alien's symbol underneath it.

"We don't love aliens, do we?" asked Ariana, trying not to giggle.

"Naaah, let's try something else," said Jimmy. "Hmmm…Oh, I got it!"

He switched the switch a third time as the lights read "Free Parking."

"Wow Jimmy! That is awesome!" said Ariana. "Do you think the aliens can really read this message from outer space?"

"I'm sure it will," said Jimmy. "Now let's turn up the juice of the electricity and we'll be done."

Jimmy tried to make the message brighter, but doing that caused a short circuit as all of the power inside the houses of the Retroville residents went out.

"Oops," said Jimmy.

Then a second short circuit shocked from the power line as Jimmy and Ariana fell off the Hover Car. But as they were about to fall to their deaths, they fell through the chimney of Jimmy's house and landed in the living room as they were completely covered with black, dirty soot.

"Santa Claus!" said Hugh Neutron, who was Jimmy's father. "You're early! Where's your wife, Mrs. Claus?!

Ariana landed on her bottom on the floor.

"Owww!" said Ariana, getting up.

"There she is!" said Hugh.

"Jimmy, do you mind if I go home and take a bath?" asked Ariana, trying to wipe the soot off her clothes.

"Don't mind that at all," said Jimmy. "I might as well take a bath, too. See you tomorrow, Ariana."
