I was in the grocery store today — the same one as before.  I was wearing my Pink Floyd shirt with a prism on the front.  The title of the album associated with that prism was printed across the top.  The courtesy clerk took special notice of it.

“What does your shirt say?  ‘Dark Side of the … Movie?’”

I faltered, but regained my composure quickly.

“‘Dark Side of the Moon.’  It’s one of the best selling albums of all time.  Came out in 1973,” I said.

“Album.  Huh,” he said.

Being the non-violent type, I just walked away.
