Radio joke

A long time ago there used to be a radio show in Scotland on a Sunday presented by ( I think) Andy Cameron. I can't recall which station it was, but some of you might remember the banal nature of the jokes he encouraged children to phone in with. He always liked beating the kids to the punch line 'cos invariably he (and all the rest of us) had heard the jokes before.

That was until one Sunday when a young lad fae Forfar phoned in. The conversation went vaguely like this.

Boy: Andy I've got a joke for you.

Andy: go on then.

Boy: what vegetable makes your eyes water?

Andy: that's easy. It's an onion.

Boy: no it's a turnip.

Andy: turnips don't make your eyes water. (He falls right into the trap here)

Boy: you've obviously never been hit in the baa's wi a neep.

- Cue instant music to hide Andy's loss of the plot, the hilarity in the studio and the laughter around our house. Even after the music finished, Andy couldn't speak properly. 

Classic!
