Man 1: Thanks for picking me up... Man 2: No problem, Mack. Man 1: You know I've always wanted to find out what a truck driver is like... Man 2: Oh, we're pretty much the same as anybody else. Man 1: Really? Are your goals the same? What exactly are you looking for in life? Man 2: Well, basically I guess I'm looking for America... Finding America has become kind of a quest for me... I keep thinking it's going to be around the next bend... But I'll find it, I know it. Man 1: Fantastic! Please take me with you Mr. Truck Driver. I, too, want to find America! Man 2: O.K., you can join me in my search for the truth. Man 2: Well, Frankie boy, you've done it again! This one looks dumb enough to pay the tolls clear to Los Angeles.
