Roxxy and MC walk into the police station...
Cop: Young man, if you will wait over there...?
Roxxy: NO! I mean, I want him to stay...
MC: Yeah, I'm the brains of this operation. ...The brawn too now that I think about it. Not to mention, I am also the financier and the charismatic one...
Cop: What does that leave for her to do?
MC: Oh? She's the one with the tits!
