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

10. The D.E.N.N.I.S System

Season 5, Episode 10 

Best Quote: Dennis: "Wrong! Wrong! Wrong! Wrong! You were supposed to let her get stabbed, hope that it hits a major artery, and then as she's dying you nurse her back to health, thereby making her totally dependent on you."

The D.E.N.N.I.S system is probably the most misogynistic, sexist and creepy way of engaging women that has ever been invented. Dennis reveals that he has a 'foolproof' way of making women fall in love with him before subsequently break their hearts.

The episode focuses around this and the gangs attempts at trying their hand at the D.E.N.N.I.S system in their own unique ways. 

This is one of the most offensive episodes towards women, as it suggests that any woman can be manipulated by any man at any time, by simply following a few steps dictated by a narcissistic sociopath. The gang end up taking advice such as allowing organised stabbings and making terrifying phone calls to their prospective partners in order to sleep with them and then leave them heartbroken. Sound familiar anyone? If so, you've been D.E.N.N.I.S'ed.
