I also remember this verse:

Sambo had an aunty, an aunty very poor
Who one day gave to Sambo,
a rotten apple core.
Sambo didn't want it
so he ran upstairs to bed.
He trod on a stair that wasn't there
and fell and broke his head.

Oh! More work for the undertaker
another little job for the tombstone maker
Off to the local cemetery
on his tombstone you will see
"Sambo, that's me"
