I believe one of the missionaries in our mission found a guy that was wearing a shirt of an Utah high school wrestling team. The shirt had all the wrestlers’ names on the back, and he found his brother’s name on the shirt.
I taught a guy who was wearing a Young Women’s shirt when I first met him. It had that flame logo with the Christlike attributes circling it. Something like that. The dude couldn’t care less he wearing a girl’s shirt, he was happy to have it.
My very first day in my first area, very first person I saw was a little kid wearing a BYU shirt. I got all excited thinking he was actually a BYU fan, but I quickly learned it was just some random kid. I’m not even sure I saw anyone else wearing BYU stuff the rest of my mission (other than missionaries).
