My favorite is one I bought some years ago, and was already approaching 2x. It too is a college jock t-shirt, big, simple lettering, marked XXX etc.
It's for the Electoral College athletic department.
Think about it . . . .
I bought it after the 2000 election when Hitlery was running around claiming she was going to do away with the Electoral College after AlBore was denied his rightful place as president by that pesky Electoral College.
