My Pixies t-shirt has recently gotten, "Pixies rule!" and "What are you gay?" responses from complete strangers. (To wit I've responded "Don't they though" and "Fuck off, little boy" respectively.)

What sort of rock music paraphernalia do you have?

I'm thinking my as-yet imaginary record store ought to carry cool band tee's. Everyone likes to show off their favorite bands so it's weird record stores (in the states at least*) don't carry much in this regard.

* I had wondered whether this was something that couldn't be overcome because of licensing or whatever, but then in an HB punk record shop they've got all sorts of old time t-shirts, from the Germs to UK Subs to whatever. And I see the kids wearing DK shirts knowing full well they've never heard the Dead Kennedy's but that's for another thread.
