A new episode of Bob's Burgers, titled "The Equestranauts," airs tonight on Fox. In "The Equestranauts," in an homage to the "Bronies" subculture, Tina attends her first Equestra-con, a convention based on her favorite animated pony show, "The Equestranauts." To her surprise, she finds that the show's fans are middle-aged men (called "Equesticles"). When a powerful super-fan tricks Tina out of her rare toy pony, it's up to Bob to go undercover to get it back. The voice cast includes H. Jon Benjamin as Bob; Dan Mintz as Tina; Eugene Mirman as Gene; Larry Murphy as Uncle Teddy; John Roberts as Linda; and Kristen Schaal as Louise. Bob's Burgers, "The Equestranauts," airs Sunday, April 13 at 7:00 p.m. ET on Fox.
