I get that at least once a day when i wear my Gaslamp Ball t-shirt. It's a snazzy top so I wear it often, almost as much as my Combat Sambo shirt and my Meet the Feebles shirt.
So far I've gotten "Are those winning lottery numbers?" and "What the hell is on your shirt?" Not a lot of creative questions. One person guessed correctly what it was, quite nice. Anyone else had any interesting shirt talk? If this has already been covered, forget it.
