My oldest daughter recently started dating. She thinks I’m being anti-social.

Dads, I can make this t-shirt for you.  I’ll even put your daughter’s name on it.

“You can date my daughter, but only if your jiu-jitsu is better than mine. good luck, punk.”
Update: This is the original that has been copied a bunch of times. I posted a cropped version of this to one of Tom DeBlass’ facebook posts about his daughter, then the ADCC page posted it, and that spawned at least half a dozen t-shirts. People either love this or hate this, but this phrase traces back to me.
