Mugs not drugs! Cheers to a fun St. Patrick's Day! This mens st patricks day tshirt is a funny way to show off your plan for parade day. Grab a large, frothy glass of green beer and sway along to drinking songs in your favorite Irish pub. St. Patricks day has already passed? Why not wear this funny graphic tee all year long- its a great conversation starter at keg parties, at your local brewery and among fellow beer aficionados.
