Harry Boardman recited this in a series of Kid's songs and rhymes that he used to do and is recorded on "Golden Stream" - sadly well out of print although I think there may be cassettes of it floating around somewhere.

"Have yer ever had yer 'and in a mangle
And some silly bugger turns the 'andle?
Yer wrist goes flop and yer 'and drops off
Have yeeer .. ever had yer 'and in a mangle?"

The pause in the last line was put in by Harry - I suppose you had to hear him do it!

Cheers
