If you think sparring with a judge during oral argument is tough, try sparring with a judge in a gym, in a sport featuring spin kicks, and a referee that yells “fight!”

Justice David Medina’s biography notes that “in college he competed on the university’s karate . . . team.”.

He really wasn’t kidding.

Turns out, he recently participated in a match — with a law clerk. Tickets to the match were a featured item at the Court’s annual holiday charity auction.

Thanks to the power of YouTube, you can watch from the comfort and relative safety of your office.
