I loved this one from my childhood...
On Top of Spaghetti, all covered in cheese
I lost my poor meatball when somebody sneezed
It rolled off the table, it rolled on the floor
And then my poor meatball rolled out of the door
It rolled in the garden and under a bush
And then my poor meatball was nothing but mush etc, etc.
And how about....
When father papered the parlour
You couldn't see him for paste
Dabbing it here, dabbing it there
Paste and paper everywhere
Mother was stuck to the ceiling
The kids were stuck to the floor
You never saw a blooming family
So stuck up before!
Oh, and another one: 'She wore an itsy bitsy teeny weeny yellow polka dot bikini'.
