two police officers in discussion, after one of their fellow officers go off on a foot
chase:
officer a): where'
s my partner Michael?, you seen him?
officer b): i think I saw him on it like a car bonnet, chasing after that
hot female teenage delinquent.. (moments later): Tom, here goes the answer to your question, there's Michael, on it like a car bonnet; i don't think we should be disturb him (pointing at a car
parked some distance away). He is on it like a bonnet, raping that
girl, instead of giving her a hefty fine. I hope they become a cute little couple, lol.
officer a) Thanks man, well looks like that
girl didn't have the money to pay the fine anyways, so she got what she deserved. Let's just hope she doesn't have a beautiful disaster. Hang on partner, let me call me my wifey, tell her aqbout Michael and his big fish.
officer b): don't call your wife with such nonsense, you buckwheat brains; she
may be on it like a car bonnet, probably playing bingo with her girlfriends or
whatever.
