Everyone knows the famous Homeland Security t-shirt -- it's a picture of Geronimo and three other Natives with the tagline "Fighting terrorism since 1492" -- but it's just one of many sly shirts that we've spotted on in-the-know Natives.

There is irreverence here, and even jokes -- but the humor packs the punch of truth.
