This one from RandR is pretty flippin awesome. Without the title of the shirt, it will probably only look like a 3-d owl with a gun (sans 3-d glasses), but I’m totally cool with that.
I’m also transferring to Temple University, whose mascot is the owl, which gives me an extra connection to this shirt. Our mascot doesn’t carry a gun though (unfortunately).
You can pick it up for $14.00 at RandR. Sadly, sizes are somewhat limited (they don’t have my size ).
