Anyone who's been to a GWAR show knows that the only true "GWAR shirt" isn't sold at the merch booth - it's whatever shirt (preferably a white cotton one) that you wore to the show, forever after stained by fake blood, fake semen, and real sweat.
I've only gotten to see them twice. It won't be the same without Slymenstra though. They're gonna be doing some shit in NYC pretty soon, which is only like an hour away :D
I've seen them seven times, the last without Slymenstra on stage, but I saw her after the show. She and Don Drakulich (Sleazy) haven't been doing the stage shows but they're still there having a blast. Don hurt his back for a while (he's an amazingly tall guy without the prop shoes) but started touring again in 2008 but isn't nearly as active. Back stage these guys are really humble and awesome people.
