On today's Weakest Link

"Who was the author of the poem that begins 'They muck you up, your mum and dad'?"

I don't think they'd have taken my answer of "there's no such poem".

As a sidenote I did a check on this bowdlerised version and discovered several websites repeating it, some without mentioning the fact that it had been changed.

This page mentions an even more bowdlerised version: They tuck you up ... which also destroys the meaning.
