On the sixth season of It’s Always Sunny in Philadelphia, the gang of five reprehensible sociopaths engaged in their typically awful behavior with very few repercussions. The hilariously selfish acts from Dennis (Glenn Howerton), Mac (Rob McElhenney), Charlie (Charlie Day), Dee (Kaitlin Olson) and Frank (Danny DeVito) included a pregnancy for Dee (to incorporate actress Kaitlin Olson’s real-life pregnancy), marriage and divorce for Dennis and a stint as a janitor for Charlie.
