The gang returns for their most inappropriate adventures yet in Season 9 of It's Always Sunny In Philadelphia. Once again, Paddy's Pub is the spot for clever cruelty and tasteless tomfoolery as Dee and Charlie get roped into a pyramid scheme and Dennis reveals he has super-powered erections. Season 9 also features "The Gang Saves The Day," the show's historic 100th episode. While trying to "stop" a convenience store robbery, Frank hotdogs it, Charlie gets animated and Mac takes a ninja star to the neck!
