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

The episode features Howerton's real life wife, Jill Latiano, as the subject of the titular system.

The titular system is followed up in the fourth episode of the sixteenth season, "Frank vs. Russia" Dennis (Glenn Howerton) walks in on Mac (Rob McElhenney), Frank (Danny DeVito) and Dee (Kaitlin Olson) asking Charlie (Charlie Day) about the Waitress (Mary Elizabeth Ellis), whom he is in love with, and plays them a voicemail message of a woman, Caylee (Jill Latiano), who says she hopes he dies.

Dennis explains that he met Caylee at the pharmacy when he pretended to buy pills for his sick grandma , which is the first step of the system (Demonstrate value).

Dennis romantically shows up to Caylee's window and begs for forgiveness (Inspire hope), and they later have sex again, before he sneaks out in the middle of the night with the intention to never talk to her again (Separate entirely).

It was received generally positively, with IGN saying "Always Sunny was out in full force", although contrastingly stating "a large chunk in the middle ... just felt flat".

Club called it an "amusingly intricate plot", while also commenting on it being "little lighter on laughs than" the previous episodes, and giving it a B+.
