Saturday Night Live

NBC | 9:00 pm

Culled from this Emmy-winning late-night comedy show's long run, the two-hour "A Saturday Night Live Christmas Special" — a perennial holiday hit with fans — offers a cavalcade of favorite yuletide-theme sketches performed by Kenan Thompson, Kate McKinnon, Mikey Day, Aidy Bryant and other veteran "SNL" cast members from seasons past.
