This is one my dad used to say to us and my mother would say “OH Don!!!!”:
There was a little puppy dog, a puppy dog was he,
he picked up his little leg and piddled up a tree.
Because the tree was smoking, he thought it was on fire,
so he picked up his little leg and piddled a little higher.
Hi, my mum told me this from the time i was very small:
Listen, listen, the cat is pissin,
Where, where, under the chair,
Run, run, get the gun,
Its okay, she’s all done.
Our parents seem to have the same sense of humour!
