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.

Yeah, signage used to be massively more important. Not just the intersection signs, but the mile markers, the signs that give you a general guide to a distant hospital or park, the signs on overhead bridges that tell you what that cross street is. You'd have to constantly note them.
The compass was a lot more important, to the point where people installed aftermarket compasses in their car if there wasn't one already. Also there was a lot more math with address numbers, like noting which side of the street had odd numbers, then counting how much they were incrementing to estimate how close you were. Resetting your "trip odometer" could be important.
There was just a lot more "dead reckoning" type of shit. GPS made all of this stuff so much easier. I do miss the AAA Triptiks though. My Grandma had AAA and she would get them for me. There was something really satisfying about working your way through one on a long road trip.
