It's Always Sunny In Philadelphia: 10 Best Recurring Jokes
3. Dennis' Erotic Life
Dennis Reynolds started as the "cool guy" in Always Sunny. He was always hooking up with chicks, impressing people and acting vain; but that man is long gone now. A great example of how far he has fallen is the ever-evolving creepiness in his erotic lifestyle.
The sex life of Dennis Reynolds is - weirdly - one of the most interesting things about the show, as his constantly domineering and creepy behaviour is always eye-catching. This was brought to the forefront of the series in the episode "The D.E.N.N.I.S System", where he walked the gang through his six-step plan of seduction. But his flair for manipulation was only just getting started.
He's also resorted to using tapes, video cameras and even elaborate sex rooms (as seen in The Gang Escapes) for his sinful ways, and hearing stories of his "conquests" - as he calls them - is always an amusing yet disturbing joke.
And, of course, it would be impossible not to mention "the implication", which has reared its ugly head plenty of times throughout the show and never fails to get viewers rolling in fits of laughter whilst rolling their eyes too.
