release dates of TV series It's Always Sunny in Philadelphia

It's Always Sunny in Philadelphia follows five egocentric friends who own and operate Paddy's Pub, a dive bar in South Philadelphia. The group consists of Dennis Reynolds, a vain narcissist; his twin sister Dee, an aspiring actress; Charlie Kelly, the bar's illiterate janitor; Mac, an insecure self-proclaimed tough guy; and Frank Reynolds, Dennis and Dee's wealthy, morally corrupt father who later joins the gang. Each episode typically features the gang concocting elaborate schemes to solve their problems or achieve their selfish goals, which invariably backfire due to their incompetence, lack of self-awareness, and complete disregard for social norms. The show is known for its dark humor, satirical take on controversial social issues, and the characters' utter inability to learn from their mistakes or grow as people. Their exploits range from wildly unethical business practices to absurd personal vendettas, all while remaining completely oblivious to how terrible they are as human beings.
