Rob McElhenney who plays Mac on the FX comedy series “It’s Always Sunny in Philadelphia” has been in the gym quite often with Donald “Cowboy” Cerrone and crew.
Cerrone posted a fun video to Instagram where it almost seems like the two are working on stunts and camera angles at the gym. Check out the fun video where Cowboy says a quick hello to McElhenney’s wife after knocking him out of site.
