I figured I'd post this here, despite its mild political incorrectness. It's just something I drew on a whim after playing a session of Trail of Cthulhu - and thought it was witty enough to put on a shirt.

If you care to own one of the shirts (I won't be insulted if you don't, it's pretty niche!) you can grab it in ringer-T form at my CafePress:
