Wondering what the Dallas Cowboys were doing their with bye week? Quarterback Tony Romo made a surprise guest appearance at Oddball Comedy and Curiosity Festival at Gexa Energy Pavilion in Dallas Sunday, introducing the always hilarious Amy Schumer for her set.

"I want you guys to know, she had a cameo role in my movie Trainwreck, she did great," joked Romo. "She was only on screen for a couple seconds, I had to carry the load; but I was thoroughly impressed, I invited her back tonight."

Headlining comedian Aziz Ansari had some fun with it too. 

"Tony was supposed to introduce me too, but he got hurt backstage," Ansari said, eliciting laughs from the crowd and himself. It was just too easy.
