During almost every game of UNO, someone has to object that the winner didn't say UNO! And the so-called winner objects, "I did! I did!" 

We were sitting around the campsite and another family nearby was playing UNO. We hear all the kids yell "You didn't say UNO! You didn't say UNO!" and we just have to laugh because it's just like that every time we play. It's a universal right to declare the winner didn't say UNO. So we thought we should put it on a shirt so that everyone can have a little chuckle to themselves when they see someone wearing it.
