Today is Glenn Howerton’s birthday, so what better way to celebrate than with this supercut of his finest work on It’s Always Sunny in Philadelphia? Namely the deranged and psychotic monologues of everybody’s favorite psychopath, Dennis Reynolds. Or, as he says, “This is about much more than just business. This is about the thrill of wearing another man’s skin.” I think Reynolds’ is a skin we’d all be too traumatized to ever come back from.
