Hi Guys,
I know it's not a classic clue, but I thought I'd enter it because the episode of DTDD where it occurred was very funny.
For those that didn't see it, the newsreader had been struggling over the clue all day, to the point where he was on the verge of a breakdown - constantly repeating "gegs", gegs". Then in comes a courier, overhears him and blurts out the answer.
It ends with the newsreader in a taxi chasing the courier all around London.
