Taking It Lying Down

J: Dude, with your passenger seat tilted all the way back, I feel like I should take a nap.
F: Uh huh. Hey, don't I turn here to get back to the freeway?
J: Yes. But you need to go left, not right.
F: What are you talking about? I'm in the left-hand lane.
J: Oh. Yeah. Well, I was having trouble seeing the road, what with being in this unique position. You know, prone.
F: Prone? To what?
J: Lying.
F: *pffft*.
