I'm always on the prowl for cool T-shirts. Check out these three Watchmen T-Shirts. What makes them cool? Because they're the equivalent of a comic book inside joke. Folks not "in the know" will have no idea what these T-shirts are all about. A red blob on a yellow T-shirt? Random black spots? Two black circles on a blue shirt? But comic book fans everywhere would see you and nod their head in recognition. Nowhere on these shirts does it say "Watchmen!" which makes them under-the-radar geek gear goodness.
