I seem to be unique in that my wonderful Mum used to sing me rude songs:-

Oh what fun
oh what fun
Shooting peas up a nanny goats bum

Gemima Jones and me
we both sat up a tree
We had no shimmies
to cover our jimmies
Gemima Jones and me!

Mrs McGuire
weed on the fire
the fire was too hot
she weed in the pot
the pot was too round
she weed on the ground
the ground was too flat
she weed on the cat
And the cat ran away
with the wee on its back!

The corporation muck cart
was full up to the brim
The driver over toppled
And then he fell right in!

Quakers meeting has begun
Sing, dance fart or run
Show your teeth
Or whistle!
