I've been a rabbinical student too long

Pulling up to a stop light today near the University of Cincinnati campus, I saw an older man at the crosswalk. He had dark hair and was wearing what I thought was a light-colored kippah, situated perfectly on the crown of his head. How neat! I thought to myself. Three or four scenarios ran through my head in the space of a second: maybe he was a visiting rabbi at HUC, maybe he was an HUC grad student or prof going to UC for a class , maybe he was a random Jew walking by, etc.

What really happened? What did I see when I pulled up closer?

Yeah, you guessed it. It was an older man with a perfectly round, perfectly kippah-situated, bald spot.
