About T-Shirt Design
Got Guitar T-Shirt is funny without trying way too hard, which is probably why the idea works. It fits really well with everyday humor, but you do not have to be obsessed with that stuff to enjoy the joke.
You could wear it for birthdays, bring it out for holidays, or just keep it in the normal shirt rotation. It has the easy look of a graphic tee that lets the saying do most of the talking. It is simple, funny, and easy to picture on someone who likes this kind of humor.
