HOUSTON -- For an upcoming segment on NBC's "Weekend TODAY," a rather famous Houston Texans defensive end got all dressed up.

As Batman.

Yes, J.J. Watt -- who was turned into a comic book character, Megawatt, by one of his sponsors -- recently donned a Batman costume to surprise kids at Texas Children's Hospital this past Tuesday afternoon. Visits to hospitals are standard for Watt on off days, and he usually makes them discreetly.

This Tuesday, Watt stopped by Texas Children's Hospital's for a Halloween party. He spoke in a husky Batman voice as he shook hands with several adults. He posed with his batwings outstretched. He signed autographs. He participated in party activities: foosball, decorating pumpkins, etc.

The Texans' official website posted this video of the visit. The full segment will air on Sunday morning.
