About T-Shirt Design
There is a nice, simple feel to Worlds Funniest Grandfather T-Shirt that keeps the joke from feeling overdone. The design connects with grandpa humor in a way that feels obvious but not overdone.
You could wear it for Christmas, bring it out for Father's Day, or just keep it in the normal shirt rotation. It has the relaxed feel people usually want from novelty shirts without getting too complicated. It has enough personality to be funny without looking like it is begging for attention.
