About T-Shirt Design
Come To The Dark Side We Have Cookies 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 makes sense for holidays or birthdays, especially if the person already likes this kind of humor. The graphic tee style keeps the whole thing casual and easy to understand. If you already like funny t shirts, this one fits right in without feeling like the same old joke. It has enough personality to be funny without looking like it is begging for attention.
