About T-Shirt Design
I May Be Crazy But Crazy Is Better Than Stupid T-Shirt works because it sounds more like something a real person would say than a random slogan. It has a clear everyday humor vibe, which makes it easy to picture as a gift or something to wear for fun.
You could wear it for holidays, bring it out for casual days, or just keep it in the normal shirt rotation. If novelty t shirts are your thing, this one has a simple joke that is easy to wear. It has enough personality to be funny without looking like it is begging for attention.
