Ep 10. Charlie Kelly: King of the Rats

In season 6 episode 10 of It's Always Sunny in Philadelphia, titled "Charlie Kelly: King of the Rats," the gang is faced with a rodent problem in Paddy's Pub. When Dee discovers a rat in the bar, Dennis, Mac, and Charlie decide to take action by setting traps and poisoning the critters. Charlie, however, takes matters into his own hands and decides to catch the rats himself, going as far as to build a rat maze in the basement of the bar.

Throughout the episode, Charlie's obsession with rats becomes more and more apparent as he spends all of his time in the basement trying to catch them. As the rest of the gang tries to deal with their own problems, such as Dee's failure to impress her therapist and Dennis's attempt to make himself look younger, Charlie becomes increasingly isolated and focused on his rat-catching mission.

Despite his efforts, Charlie is unable to catch a single rat, leaving him even more frustrated and downtrodden. It's not until Frank decides to help him out that they finally make some progress in the rat-catching department. Frank brings in a group of homeless men to help them catch the rats, but things quickly spiral out of control when the men refuse to work for free and demand more money.

As tensions rise and the situation becomes more chaotic, the gang finally comes up with a plan to get rid of the rats once and for all. However, their plan goes awry when they accidentally release all of the rats into the bar. In the final moments of the episode, Charlie emerges from the basement covered in rat bites and triumphantly proclaims himself the "king of the rats."
