scene: standing in line at an eatery in a foodcourt. early 40-ish guy with a ponytail and a sport blazer behind me.

ponytail: hey, what are you playing?
me: hmm what?
ponytail (pointing at my left hand): your fingers, looks like you were playing guitar. i play too.
me: oh cool. yeah, i do that if i'm trying to nail down a song.
ponytail: what song?
me: uhhh, it's called "we'd have a riot doing heroin" by a band called "the queers"
ponytail: oh.

he didn't say anything to me after that.
