What kind of merch do you think they sell at Metallica shows these days? We wonder if you can still get that awesome "Metal Up Your Ass" shirt — the one with the image of the sharp metal blades jutting out from the inside of a toilet bowl. Our older cousin had that shirt, and we thought it was the coolest. Then we got older and we thought it was sort of trashy. Now we think it's super cool again. Go figure.
