Made up of three parts, “The Honeymoon Stand Up Special” features half-hour sets from both Leggero and Kasher, comedians married to each other. Leggero, the star and co-creator of “Another Period,” goes first (as per an opening scripted bit). Kasher, the host of the late night series “Problematic,” follows close behind, setting the stage for a third episode that sees the two performing together.
