John Mulaney has a long and storied history with Saturday Night Live; as the co-creator—and frequent breaker—of Bill Hader’s beloved Weekend Update correspondent Stefon, Mulaney spent six years on the show’s writing staff, filling it with some of its strangest, funniest jokes of the last several years. Outside the occasional rare cameo, though, Mulaney’s never spent much time in front of the show’s cameras. That’s about to change, with NBC announcing that the celebrated stand-up will be hosting the series for the first time on April 14.
