It's Always Sunny In Philadelphia

Its movie night and Mac and Dennis plan to watch Predator for the thirtieth time that month. The two plan on making popcorn but needed a bowl so they go to Dee's apartment to borrow a bowl. Once they arrive, Dee starts joking about Mac and Dennis' inability to live without each other for an extended period of time. The two laugh it off but things start to get tense and Mac moves in with Frank and Charlie.
A lonely Dennis pays a visit to Dee. He asks her to watch a movie with him, but she can't because her cat somehow got stuck in the walls and she's trying to get him out. Mac is disgusted by his new roommates – Frank cuts his toenails with a knife and Charlie is a slob, leaving trash everywhere. When Mac tries to clean up after him, Charlie leaves for Dee's apartment.
Charlie who knows so much about cats, note the kitten mittens, decides to bring more cats into the apartment in an attempt to lure the original cat out of the walls. Frank comes over to Dee's as well since he's tired of living with Mac. Dee is sick of the boys' feud and set up Mac and Dennis on a blind date. After dumping their waters on each other at a fancy restaurant, they realize they cant live with out each other.
Back at the apartment, Dee is fed up with the cats and decides to open the wall with a hammer and take it out – there are now 10 cats living inside the walls. Frank and Charlie decide to bail and go watch Predator instead.
