I really like this idea. I’ve informally done haiku on demand at parties. Doing poems on demand in public is a leap, but I think I will take it. I’m going to practice on friends first. And make up my own assignments.
I heard there’s a guy at the Temescal Farmer’s Market who writes sonnets on demand(!). If i set up there, a potential requested topic might be tomatoes. And so:
Brave souls dared eat them
those poisonous globes
red is for danger
Nightshade: not for me!
But for the intrepid
Luscious tomatoey goodness is the prize
A treasure of the new world
