Though I Think at Some Point They're Legally Obligated to Stab Me

(a BMW is blocking the bus, people inside get restless)
Guy #1 on cell, speaking to everyone on bus: Hey! What's the difference between a BMW and a porcupine? (pause) Anybody?
Guy #2, after a moment of silence: What?
Guy #1: On a porcupine, the prick's on the outside! (laughs, then on phone) Yeah! I gotta entertain the people on the bus!
