About T-Shirt Design
There is a nice, simple feel to Hooray Sports! Do the Things! Win the Poinst! Tee that keeps the joke from feeling overdone. Fans of sports humor will probably get the joke first, but it is simple enough for almost anyone to understand.
You could wear it for team events, bring it out for birthdays, or just keep it in the normal shirt rotation. It works well as a novelty t shirt because the joke is clear and the design has plenty of personality.
The graphic tee style keeps the whole thing casual and easy to understand. It is simple, funny, and easy to picture on someone who likes this kind of humor.
