In Fife in the 70s we sang, or rather shouted:

Skinny Malinky lang legs
Big banana feet
Went tae the pictures
Couldnae find a seat
When the pictures started
Skinny Malinky farted
When the pictures ended
Skinny Malinky bended

Everyone knew the last couplet was not quite up to the level of the rest but somehow no-one ever hit upon anything better.
