Cartman: Okay look, yes, I did try to tell my younger self about what he was about to do- oh god damnit! I forgot to tell him!
Dr Mephesto: Eric, you are not welcome here anymore! [starts pushing the boys outside]
Cartman: Wait, what? But I need to tell my past self about the event!
Dr Mephesto: You can't, if you do that, then you'd never have been in detention to know about my time machine, which you would've never gone back to tell yourself about the prom thing and then you would've had detention anyway knew about the time machine and so on and so on!
Cartman: But I-
Dr Mephesto: I'm sorry Eric, but it's too damn risky! [shuts door]
Cartman: ...GOD FUCKING DAMNIT!
Butters: Come on, Eric, I'm sure there's another way to get rid of your detention problem!
Cartman: Come on!
South Park Bus Stop, the boys except Cartman are waiting
Cartman: [arrives] Hey guys!
Stan: Hey, dude. You feeling better after what happened yesterday?
Cartman: Why, what happened yesterday?
Kyle: Yesterday, you were talking about how you had these 'bogus' nightmares
Cartman: Oh that? Yeah, I've gotten over it. Hey did I ever talk about seeing my future self once? [Stan and Kyle think for a moment]
Stan: ...Yes
Cartman: Oh, really?
Kyle: Yeah, why?
South Park Elementary, Garrison is teaching square numbers.
Mr Garrison: And so that's how you square numbers! Any questions? [Cartman puts hand up] Yes Eric?
Cartman: Mr Garrison, why does it hurt so much to get kicked in the balls?
Mr Garrison: ...I don't know Eric, it just does!
Cartman: Oh okay, [glances at Stan] Hey Stan, is there a problem?
Stan: Why would you want to know, asshole?
Cartman: Woah, no, seriously, I wanna know!
Stan: Wendy's just a little upset with me because she never knew her divided bys and I offered to send her my answers which she hesitated doing at first but decided to do it, but I forgot to send her my answers so she's going to get in trouble for not doing her divided bys!
Cartman: ...Wait, you're telling me that Wendy Testaburger does not know her freaking divided bys?!
Stan: Look, she tried her best but she had to have this really long dentist appointment so she didn't have any time to do anything and I was going to fill her papers!
Cartman: So she couldn't do her homework?
Stan: Most of it was made of divided bys and she only got 3 problems solved out of like... 18
Cartman: Woah, 15 problems unsolved
Stan: I just don't know what to do
Cartman: Well you can do something, I don't know, just save her from a burning building or something? [Pete a.k.a red goth bursts into the room]
Pete: Everybody, get out! I accidentally set the school on fire!
Mr Garrison: Excuse me? [a power outlet bursts into flames] ..Gaah! How did that get there?! [everyone starts screaming and rushes out of class]
Cartman: Oh, what an amazing coincidence! [gets out of his desk and joins the crowd. Stan gets out first, a few other kids get out as well, but the roof falls and lands on Cartman's back, trapping him] OW! OW! OW!
Meanwhile, Stan and a bunch of other kids are out, firefighters have arrived.
Stan: Wait a second! [looks around] Wendy? [Stan thinks back to what Cartman said] (I don't know, just save her out of burning building or something?) [Stan goes back inside the school, he runs out of the school with Wendy in his arms, he drops her outside, gasping for air]
Wendy: Oh my god! Stan, are you okay?! [her parents arrive]
Stan: No! I gotta go back and save the others! [goes back inside the school, much to the other people's surprise]
Male Firefighter: What the hell? [Stan comes running out with Kyle and drops him, Stan goes back inside again]
Mr Garrison: [lifts finger] ...Is that normal?! [Stan comes running out with Cartman and drops him, Stan collapses]
Mrs Testaburger: Who is that boy?
Mr Testaburger: That's Wendy's boyfriend, isn't it?
Cartman: [looks at school] Wow… that was fast
