Joe Nathan attends batting practice in Tony Romo uniform after losing bet

Losing a bet is never fun.

One might even use the term humiliating.

Just ask Joe Nathan.

The Rangers closer, a New York Giants fan, was on the losing end (in case you couldn't tell) of a friendly bet with teammate Mike Adams, a Dallas Cowboys fan.

Both players agreed that the loser would have to wear the uniform of the winning team's quarterback.

The Cowboys defeated the Giants in the NFL season opener, so Nathan kept his end of the bargain, and MLB Network caught him attending Tuesday's batting practice dressed as Tony Romo.

We're just grateful the bet wasn't over cheerleading outfits.
