Man 1: Hey, how do I get to the Citgo?
Man 2: Yeah, well. See those trees down there? Take a left after the trees, then go past the brick buildings for about half-a-mile and take your next right. Once you hit a stop light, get in the left lane and turn left. The road will kind of veer right and then you'll see a church and after that you'll see the Citgo, on the right.
Man 1: So... Left, right, left, right?
Man 2: Uhh, yeah.
Man 1: Thanks. (Underbreath: F*ckin' Rube.)
