In this episode Butters is visiting Niagara Falls as a tourist, but he is arrested for being a foreigner. Nobody cares about his passport or the fact he was there "legally" and he gets funneled into a huge prison facility called "Alberta Alcatraz".
After several scary experiences he is in line for a phone call. When he gets to the front the guard pretends to not understand what he is asking for.
- Guard: WELL, what do YOU WANT?
- Butters: Uhh I want to make a phone call, please.
- Guard: Puh-hone call? Puh-hone? What's that?
- Butters: I don't understand mister. I'd like to call someone on that phone.
- Guard: Oh THIS? DO YOU MEAN-
The guard lets out a long, trumpet-like fart that sounds like, "fooooooooooone".
- Butters: Wha--- what?
- Guard 2: YEAH! YOU MEAN- (farting) foooooooooooone!
Apparently this is how Canadians make the word, "phone".
- Guard 2: HEY THIS LITTLE YANK CAN'T SAY- (farting) ffhhhooooooone!!
- Guard: HAHA!!! (farting) fuuuooooooooooooooone!
All guards start laughing at Butters and farting "fooooone". They can all apparently do this quite naturally.
- Butters: B-but, I don't have to fart right now.
- Guard: IF YOU WANT SOMETHING YOU NEED TO LEARN TO SPEAK CANADIAN!
Butters resolves to save up his farts to get his phone call. Several days pass. Now trembling and sweating, a pale Butters can barely stand in line.
- Butters: Oh man... I gotta make it...
The inmate in front of him effortlessly farts "foooooooooone" and is let ahead. Butters is up.
- Guard: YEAH? WHAT DO YOU WANT THIS TIME?
- Butters: I want... I want... I... uh... UH.... ahhH!!
Butters loses control of his bowels and sprays shit in all directions, then collapses. Everyone around yells in disbelief and disgust.
A large inmate walks up and looks down.
- It's OK little buddy, my cousin had that same speech impediment.
Then I woke up.
Actually one of my most favorite memories because the simplicity of the solution using recursion blew my little mind. It was like discovering a magic spell.
