The hilariously sick, twisted “It’s Always Sunny in Philadelphia” will be making its highly anticipated (by me at least) return to FX in six short weeks. What could be more awesome than that? How about the cast coming to San Francisco for a live performance of Charlie’s insane rock opera “The Nightman Cometh”?

The gang is going on a mini tour next month, and will play at SF’s Masonic Auditorium on Sept. 24. Tickets go on sale tomorrow (Friday) morning, and it’s a good bet they’ll go fast. Check out the official “Always Sunny” site for more information.

UPDATE: Geez, I should have taken my own advice. The show’s already sold out.
