Another song!
We were sitting in the garden one sunny afternoon and our neighbour's Grandson, aged about five,was marching around singing.
My wife suddenly said 'What is he singing?'
I listened and replied' I can just hear his teacher saying 'Now children, how would they sing it in France?'
He was singing, Loudly:-

If you're happy and you know it do a wee-wee!

Well it only means one thing when your five!
