I'm Louis the Fly,
I'm Louis the Fly,
Straight from rubbish tip to you.
Spreading disease with the greatest of ease,
Straight from rubbish tip to you.
I'm bad and mean and mighty unclean
Afraid of no one
'Cept the man with the can of Mortein.
Hate that word Mortein.

One spray and Louis the fly,
Apple of his old mother's eye was Louis,
Poor dead Louis,
A victim of Mortein...Mooorteiin.
