About T-Shirt Design
Papa Because Grandpa is for Old Guys Fathers Day Tee is one of those designs where the saying does most of the work, and that is totally fine. It fits really well with grandpa humor, but you do not have to be obsessed with that stuff to enjoy the joke.
You could wear it for Father's Day, bring it out for birthday, or just keep it in the normal shirt rotation. If you already like funny t shirts, this one fits right in without feeling like the same old joke. If you like to buy t shirts because the saying actually matches your personality, this one makes sense. The joke is quick, the message is clear, and that is really all it needs.
