CM Punk already has Paul Heyman in his corner for his Wrestlemania match ... and now one of the hottest comedians also has his back -- 'cause the WWE Superstar teamed up with Bert Kreischer for some tag team action on "Raw!"
The 52-year-old showed off his in-ring ability once "Monday Night Raw" went off the air. After hopping the barricade and taking off his shirt in record time (of course, that's Bert's thing), he found himself face-to-face with Grayson Waller and Austin Theory.
