The shirt says "Commies aren't cool". His face with a circle red line thru it.
It's just toooooo cute!
Maybe you could just put his visage on the seat of the pants instead on a T-shirt. Then you'd not need any red diagonal slashes and circles, nor any text, for the picture location would speak most eloquently all by itself.
I have that shirt!!! You should see some of the looks I get. Priceless.
