It's Always Sunny in Philadelphia

The Gang Goes to a Water Park (12x2)

Air date: Jan 11, 2017

The gang takes a trip to a local water park, ripe with personal agendas and ulterior motives. Dennis feeds off his mantra of "the park provides" and takes on a protégé. Frank and Charlie are determined to ride every ride by any means necessary and Mac and Dee get stuck in a tube slide for most of the day.
