While his long-awaited “Zoolander” sequel continues to, well, gestate, Ben Stiller revived his dimwitted male-model character for Comedy Central’s autism benefit, Night of Too Many Stars. Stiller took the stage as Derek Zoolander at the Beacon Theatre — alongside Jon Stewart and Tommy Hilfiger — to promote a signature, and fictitious, “Derek Zoolander the End of Syphilisation calendar,” or, “the last year of the Maya Rudolph calendar.” Stiller reeled off special dates marked on Zoolander’s calendar including, “Black History Month, where we celebrate the color black and how it makes you look super-skinny,” and “Post Apocalyptic Yom Kippur.”
