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.
