Want to promote science? Some of these T-shirts are probably good for that… others are probably a bad idea. The T-rex burger one is pretty funny. There’s also a set of "Teach the Controversy" T-shirts that are parodies of the creationists’ desire to "teach the controversy" of evolution. If you are a creationist, you may not find them funny.
Another weird T-shirt asks "What would Nietzsche do?" The answer to this is actually "Get kicked in the head by a horse and then use a lot of exclamation marks!!!!" but I doubt anyone wants to hear that.
Blizzard sells World of Warcraft t-shirts that can feature your character’s name and guild crest. I wouldn’t ever wear one of these for two reasons: 1. I hope to go on a date some day, and 2. My guild changes its crest every week, because I get bored easily.
To really make people do a double-take, wear FrankEinstein.
Some people really, really love cats. With hollandaise.
And here’s a campaign T-shirt we can all get behind. Taste we can believe in!
Finally, the gamer’s version of the Last Supper. A lot of people I knew at Seminary would giggle like crazy at this T-shirt, and as a theology nerd I thought it was pretty funny too.
