About T-Shirt Design
I'm Not A Robot T-Shirt works because it sounds more like something a real person would say than a random slogan. Anyone who is into everyday humor will probably understand the idea right away.
It could be a fun gift for birthdays, holidays, or just because you saw it and thought of someone. This is the kind of idea that works well on novelty shirts because you can understand it right away. It has that sarcastic t shirt attitude people like when they want something a little more blunt. The joke is quick, the message is clear, and that is really all it needs.
