The first trailer for the upcoming FX comedy “The Comedians” is as meta as the show itself.

The “FX original comedy about an FX original comedy” stars Billy Crystal and Josh Gad as versions of themselves. The show follows the veteran and amateur comedian, respectively, as they fumble their way to starring in an FX sketch show.

“Comedy is like heart surgery,” Gad tells the camera. “It gets botched all the time.” This is right after he pulls a ringing cell phone from his oversized diaper while filming a scene for the show within a show.

“The Comedians,” created by Larry Charles, who wrote for “Seinfeld” and executive produced “Curb Your Enthusiasm,” premieres April 9 on FX.
