Guest, Guesting, I think you screwed up there on the rhymes. I notice that amends and friends DOES rhyme which doesn't work with the rest of your composition, so I would suggest a modest change. It also scans too well, so let's try this instead:

There was a fellow called Mort
Who's testicular appendages were somewhat on the small side
So to make amends
He and some of his other buddies
Glued a Vacuum Cleaner to his shoe.

See....With just a little more work, it's a complete fuck-up! Happy to help, no need for thanks!
