The Tetragrammaton Cleric t-shirt, perfect for anyone open carrying a Beretta. Equilibrium, what a wonderfully silly movie. Via Lawdog.
UPDATE: On the topic of clothes and carry, don't wear prominent pro-2nd amendment t-shirts and hats while concealed carrying. If they're smart, people will connect the dots and take a closer look. They will most likely find telltale budges if you are packing.
