A young man and his girlfriend are walking along a street at night when they see a youth being kicked in by three other youths.
Our hero is about to intervene when his girlfriend checks him.
GIRL: No, darling, use your mobile
YOUNG MAN: Yes, I suppose you`re right.
He TAKES OUT his mobile, points it at the attacking youths in turn, and uses it like a star trek phaser to zap them out of existence.
The stricken youth manages to get to his feet, gives a big thumbs up to the couple.
YOUTH: Thanks, mate
the end
(that was one I used in my yet unproduced pilot themed sketch show;WAKE UP AND SMELL THE MILLENIUM`-oh, well, maybe you just had to BE there.)
