I was once in a comedy club, in the audience. (True story). The act in question was obviously one of theose agressive types, take the piss out of the audience. You know the ones. Well, He had a real go at me. All evening, which was a shame, as I was there with some friends and otherwise having a very nice time, except for the barrage of serious verbal abuse off this guy. Anyway, eventually he gets to: "so what do you do for a living"

I countered with:

"I work for a theatrical agency" (true, at the time)

The silence was...

....very funny.

Anyway, he ruined my evening, so I knackered his act. The tosser's on channel 4 now.
