FXX’s It’s Always Sunny in Philadelphia shows no signs of stopping, already booked for three more seasons, but one has to wonder if the decade-strong cast will ever run out of ideas. Certainly not in 2017 at least, as Charlie Day teases everything from water parks to another musical in Season 12.

Day offered a couple of teases from the 2017 season to Red Carpet Roxy, the most notable of which promises another musical to follow the infamous “Nightman Cometh.” Day didn’t 100% specify if the gang would mount another musical production, or if the episode overall would serve as a musical, but see for yourself below (via UPROXX):

It’s a funny year. You can expect to see some of the UFC, you can expect to see an entire musical episode, guest starring from Scott Bakula, you can expect to see us at a water park, you can expect a very funny season.

The 2008 “Nightman Cometh” likely stands as the series’ most enduring episode, even launching its own musical tour, but will Glenn Howerton, Katlin Olson, Rob McElhenney, Charlie Day and Danny DeVito manage to top it? Feel free to get that tune stuck in your head once more, and stay tuned for the latest on Always Sunny Season 12.
