Author's note: I'd received a review about the last part of the CHAPTER 16 was a bit confusing. I don't know what part was the confusing one, X666, but I bet it was Beavis & Butthead's laugh. Ok, I had to do this "HUH...HUH...HUH..." or "HEH...HEH...HEH..." thingy to imitate B&B nervous laughs that were in the show, and I don't really know another way to do it.

- CHAPTER 17 - "The class"

"What the hell are those nervous laughs?" Jimmy asked. "And who called me big head?".

All the class pointed to the two boys sitting on the back.

"We did. HUH...HUH...HUH..." said one.

"Yeah... HEH...HEH...HEH..." said the other.

"Mmmmh, you must be the famous Beavis and Butthead that the principal talked me about. Boys, can you come over here in the front, with your desks?" Jimmy said.

"Huhh...." Butthead said. "No? HUH...HUH...HUH...".

"That's ok" said Jimmy with a sarcastic smile. "My Neutronic Super-Powered Crane will do it for you".

As he said that, a crane came to Beavis and Butthead and, while both were screaming, the crane pulled their desks to the front of the class. Beavis and Butthead became dazed.

"Wow! HUH...HUH...HUH... That was cool! " Butthead said, still dazed.

"Yeah, HEH...HEH...HEH..." Beavis said, still dazed, too. "Let's do that again!".

"Mmmmh..." Jimmy said in his thoughts. "Maybe they're stupid, too, I can use them for my experiments".

"Professor?" a girl with glasses, green jacket, black skirt and a sad face said while raising her hand. "Can you tell us how did you make that deadly machine of yours?" she asked.

"Oh, no, no, it's not deadly. It's only a crane for idiots" Jimmy replied. "What is your name?".

"Daria" she said.

"Diarrhea, cha, cha, cha! Diarrhea, cha, cha, cha! HEH...HEH...HEH..." Beavis started to sing.

"HUH...HUH...HUH... That was a good one, Beavis... HUH... HUH...".

"You two, shut up! Especially you!" Jimmy yelled and pointed to Beavis. Beavis startled, but continued with his nervous laughing. "Now, class, what did you see with your last proffesor, Van Driessen? Anyone can tell me?".

"We were viewing such things about not to hurt animals" someone said in the back, as he stood.

"And how important is to not using cars" someone said in the middle, as he stood.

"And how important is to preserve Beavis life... errr... sorry, preserve species" someone said in the middle too, as she stood.

"Mhh... looks like Van Driessen is a member of the Greenpeace more than a professor... that things are good, but did he told how to multiply a variable times a fraction, for example?" Jimmy said.

Everyone stared at him with confused looks.

"C'mon, these are math basics!" Jimmy said, as he was trying to make the class cheer up.

"How about the atomic mass of the chemical elements?" Jimmy asked.

Everyone again stared at him with confused looks.

"What did you learn? Biology things only?" Jimmy asked.

They all nodded.

"This is gonna be a long day, I suppose!" Jimmy said as he sighed. "Class, how do you expect to approve the 3rd grade if you're not doing math, or fisics, or chemistry, or even English?" he asked.

"That's because we've never had a professor like that" Daria said as she raised her hand.

Jimmy looked surprised.

"What kind of school doesn't teach their students that things? This one? Oh, man! That's why Beavis and Butthead are assholes, too! Van Driessen had never motivate you guys to use your brain!" Jimmy said, looking concerned.

"Yeah... HUH...HUH... he was also a pervert, he was beating us out of school... HUH...HUH..." Butthead said.

"HEH...HEH... Butthead, you said 'pervert'... HEH...HEH..." Beavis said.

"I beg you a pardon? Well, I'm gonna do like I've never heard that. Ok..." Jimmy said, as he took a deep breath. "Let's start with maths. If you don't have any math books, just tell me".

"Actually, we have books" Daria said. "But they're all on our houses. We've never had to use those".

"Ok, that's not a problem. I have math books. Just let me see where I've put those on" Jimmy said as he started to look in his Hypercube.

Jimmy took some of his inventions off of his Hypercube to reach his math books. He took off his Brain Drain helmet, his Shrink Ray, his Willy Loman 3000, his crane again, his Super-Magnet, and last of it, his dog Goddard.

All the class were astonished and in shock. Beavis and Butthead were too, but they were more ocuppied in blowing out their noses.

"Wow! Man, did you build all that stuff?" someone asked.

"Holy crap! Those are the most coolest inventions I'd ever seen!" someone said, shocked.

"What about that dog over there?" someone asked, impressed by Goddard.

"Ok, class, calm down for a second! If you wanna build your own inventions like me, you'll have to study all this stuff" Jimmy said. "Goddard, please, give this books to the class" he said, and he gave the books to Goddard. "Oh, and Beavis and Butthead, here you go".

"Wow! Cool! Look Beavis... it's M...Mat... Mathem...Mathematic f-for... HUH... Dumm...dummies" Butthead said, as he read the book.

"Cool! HEH...HEH...HEH!" Beavis said. "Look, Butthead, I'm learning!" he said as he put his book on his head.
