About T-Shirt Design
So Irish My Liver Hurts T-Shirt has the kind of joke people can understand in about two seconds. It fits really well with St. Patrick's Day, but you do not have to be obsessed with that stuff to enjoy the joke.
This is an easy gift idea for St. Patrick's Day, parades, or someone who is hard to shop for but loves funny shirts. It has the same easy attitude people usually want from sarcasm shirts without sounding forced.
People who buy t shirts for the joke as much as the shirt itself will probably get what this design is going for. The joke is quick, the message is clear, and that is really all it needs.
