It comes on the 365th day of wearing the shirt.
Damn, you would at least have that bragging rights trump card if nothing else if it came before.
But I guess at least that means you get to pick the sport. I’d go with football. Start wearing January 5th, jacket weather gets you through the first few months unscathed, yardwork / pool days (where you can quickly disrobe) gets you through the summer. September through November becomes the danger zone before jacket weather kicks in again. Start switching daily rountine....Dollar General instead of Target, Huddle House instead of Another Broken Egg, etc. It’d be a grind for sure, but no one ever said winning a national title would be easy.
