It's Always Sunny in Philadelphia

The guys hire Dee's friend Terrell as a promoter for the bar and get more than they bargained for. When the waitress that Charlie has a crush on overhears him making an inappropriate comment, Charlie along with Mac seeks out black friends to prove that he is not a racist.

Charlie is skeptical and nervous when a girl from his past reveals that he is the father of their child. Though their time spent together is initially disastrous, Charlie finds an unexpected perk in acting as the brat's father. Meanwhile, Mac becomes more serious about pro-life causes when he realizes his passion for this viewpoint might get him laid. Dennis sinks to an equally low level as he uses an abortion rally as a forum for meeting chicks.

After noticing rise in underage patrons, the gang decides to make a few accommodating adjustments for their younger crowd. In addition to assuaging their concerns of morality and responsibility, it allows the gang to both turn a profit and relive their high school years with a second chance at popularity. Ultimately, they get caught up in the petty politics and crushes of the high-schoolers.

The gang learns that Charlie might have cancer and hatches a shallow-minded plan to alleviate his anguish. However, there is more to Charlie's diagnosis than meets the eye. Meanwhile, Mac proves himself a narcissist when he gets involved with a tranny to satisfy his vanity.

Upon learning that the bar's safe has been stolen, the guys take matters into their own hands and buy a gun. Shortly thereafter "gun fever" strikes, bringing out the inner-Hardy Boy in Dennis and Mac, who vow to catch the thief, and the inner-tough guy in Charlie, who uses the gun to intimidate his nagging landlord. Meanwhile, gun fever also hits Dee, as she feigns interest in guns to try and seal the deal with Colin, a crush that only seems to have mild interest in her.

Mac and Dennis pretend to be acquainted with a patron found dead in their bar in order to get closer to the dead man’s granddaughter. They reach new moral lows as the competition for her affection brings out the best and worst in Mac and Dennis. Meanwhile, Charlie acts as support for Dee as she visits her bedridden grandfather and finds himself in a precarious situation when the old man enlists Charlie in a plan, leading to a surprising discovery.
