There once was a group from Ontario.
Seriously, I once had a two-day step-on with a group from the far side of Lake Erie. I rattled off some poetry during the first day's step-on tour, and someone challenged me to make up a poem that would rhyme and would be specific to them, by the next day's tour. I worked on this into the night. Finally I recalled how a Buffalo-area radio DJ had always made fun of the town of Guelph, Ontario. He said it sounded like the voice of a diner in a restaurant, choking on his meat. "Guelph! GUELLLLPH!!"
So I worked with that town's name, which easily rhymes with lots of words. Here's the finished product:
There once was a fellow from Guelph,
Who left hot chicken soup on a shelf.
When he got back in town,
He gulped it all down.
Then he threw up all over himself.
