A man named Rob gets pulled over for suspected DUI

Police: Do you know why I pulled you over?

Rob: No.

Police: I pulled you over since it seems like you are drunk. Do you mind me doing a test on you?

Rob: Sure.

Police: You see a vehicle with two headlights behind you. What is the vehicle?

Rob: A car?

Police: Yes, but what type of car? A BMW? A Honda?

Rob: How would I know that?

Police: See? You’re drunk!

Rob: No, I’m not.

Police: Ok. You see a vehicle behind you with one headlight. What is the vehicle?

Rob: A motorcycle?

Police: Yes, but what type of motorcycle? A Yamaha? A Harley?

Rob: I don’t know.

Police: See? You’re drunk!

Rob: No. Let me ask you a question. You see a woman standing on a curb. Heels, fishnet, stockings, short mini skirt, and flagging cars down. What is she?

Police: A prostitute.

Rob: Yeah, but is it your wife, your mother, or your daughter?
