They're all guest starring on the FX channel's "It's Always Sunny in Philadelphia" on Oct. 11 at 10 p.m. ET.
Sonnen plays the role of "Dennis" alongside Haley Joel Osmont as "Mac," Xzibit as "Dee" and Andrew Dice Clay as "Frank." Having never watched the show, I'm not sure what any of that means, but it certainly sounds entertaining.
The years, however, do not appear to have been kind to the Diceman.
Anyway, when the "American Gangster" is not trying to win himself an Emmy, he'll be trying to win a fight against Forrest Griffin. He rematches the original "Ultimate Fighter" at the UFC 155 pay-per-view (PPV) event in Las Vegas, Nevada on Dec. 29, 2012.
