This is one of two pieces of comic verse included in Nine Tomorrows ("Rejection Slips") is the other. Now, I'm not a big fan of Asimov’s limericks, but the four bits of verse in Nine Tomorrows and Earth is Room Enough I adore. Here Asimov vents his frustration with a problem that pestered him all his life—where did he get his ideas from? (Even his first wife wasn’t immune to asking, hence the story "What If?".) The poem is in the form of a monologue from a fan who asks the question and then raises possible answers—drugs, alcohol, what? In the end, Asimov leaves unable to respond.

It’s a funny poem, very good indeed.
