I also own one. My players get a real kick out of it whenever I wear it on game night. I might have to get that NPC one eventually. No cash right now . . .
C'mon Dr M, you know we're not going to stop pestering you till you have honest-to-god "Sh*t" shirts out there to purchase us. Some of us still play Good characters and couldn't bear to 'soil' the minds of youngsters (or annoy thier moms! ) by proudly displaying our Gamer-wear.
Can't wait till I have the actual cash to get some of those, definately need them for the sessions. More an appropriate instead of funny sorta deal though,
