Glenn Howerton on It's Always Sunny in Philadelphia (2016)

Last night's new episode of It's Always Sunny in Philadelphia got series star Glenn Howerton naked. The fifth episode of the comedy series' eleventh season found his character, Dennis, moving to the suburbs with his roommate Mac. The two find themselves as fish out of water, unable to cope with their new pleasant surroundings. Dennis develops a hatred for their neighbor Wally who regularly brings up the warm weather every time they cross paths. Dennis imagines that he snaps at Wally, stripping off all of his clothes to confront him about his constant mention of the weather. This leads to a brief rear nude scene.
