It's Always Sunny In Philadelphia - 10 Funniest Dennis Reynolds Moments
4. Get Off With Him
Not all of Dennis's psychotic tendencies are violent.
In the episode Frank's Back in Business from season eight, the gang find a wallet in the bar. As the twenty four hour claim window passes, Dennis rummages through to find an ID and box tickets to a Phillies game. He takes Dee and Mac along with him, under his new identity as Brian LeFevre.
At the game, it appears the other guests have never met LeFevre and are interested in doing a multi-million dollar deal with the man. Dennis plays along, loving the ruse and when questioned on it by Mac, Dennis switches. The bell in the background the clearest indication of how dangerous he is.
To Dennis, it is more than just expensive Phillies tickets. In fact, it is about, and this is a quote, "the thrill of wearing another man's skin". It's an outrageously creepy scene, one which Howerton knocks out of the park as it really peels back the curtain to show how messed up Dennis really is.
It gets worse, as he then suggestively demands that his best friend and twin sister "get off" with him. As they look on mortified, it is clear that doing something this depraved is something that turns Dennis on.
If you've seen the episode, then you know that is 100% the case.
