It's Always Sunny In Philadelphia: 10 Most Disturbing Episodes

10. The Gang Goes To Hell (Season 11, Episode 9)

Only the Gang could make an alcohol-free Christian cruise dark and disturbing. While Mac tries conversion therapy on an unwitting gay couple, and Frank and Charlie cause serious damage attempting to drink boat fuel, it’s the Reynolds siblings who darken this nautical outing.

Dennis confides in Dee that he is struggling with lust, as he eyeballs a “flaxen-haired seductress”. Dee points out she looks 12. However, Dennis has somehow checked she is of age.

Rather than condemn her brother, Dee understands “the implication of being on a boat”. They are in the middle of the ocean, the girl is stuck on a boat, and she couldn’t possibly say no, because something might go wrong for her if she did.

Dee reveals her own implication. When guys she’s with get “skittish about banging”, she insinuates that it would be a shame if her account of what happened was different from his.

Dennis traps the girl in a corridor, telling her that he’s been watching and following her “in a good way”. He points out nobody would hear their screams. To somehow try to make this all okay, Dennis then blames the thunder for making his words sound sinister as the young girl flees in terror.
