What mayhem is there to look forward to in the third season of It's Always Sunny in Philadelphia? Plenty. The gang finds a live baby in a dumpster. Mac's inmate dad offers him love in exchange for drugs. Sweet Dee dates a local rap star and even gets herself set on fire. The gang tries out for the Philadelphia Eagles and the McPoyle twins hold everyone hostage at Paddy's Bar. Did we mention North Korea and the sweatshop in the basement?
