About T-Shirt Design
Pat McCrotch, St Patricks Day Shirts is funny without trying way too hard, which is probably why the idea works. Fans of everyday humor will probably get the joke first, but it is simple enough for almost anyone to understand.
This would be easy to give as a gift for birthdays, casual days, or any random day when you want to make someone laugh. This is the kind of idea that works well on novelty shirts because you can understand it right away. It has the easy look of a graphic tee that lets the saying do most of the talking. The joke is quick, the message is clear, and that is really all it needs.
