About T-Shirt Design
Jesus Was An American, Shirt feels like the kind of shirt someone would pick because the saying actually sounds like them. Fans of patriotic humor will probably get the joke first, but it is simple enough for almost anyone to understand.
You could wear it for summer events, bring it out for Memorial Day, or just keep it in the normal shirt rotation. Fans of sarcasm shirts will probably like that the joke is direct and not too polished.
The whole point is to get a laugh, and the shirt does that without making things complicated.
