 The episode, "Make em Laugh," features several references to Batman  (1989). In archival footage, the Joker is seen as Jack Napier; the  climax has the Joker taunting Batman as he hangs from a ledge, and  the Joker falls towards the ground followed by a large clown float.  Also, the episodes premise, in which comedians have alter  personalities that feature assorted costumes, is very familiar to  the casting of Micahel Keaton in Batman, who, before taking the  role, was criticized for being only a comic actor in films such as  Night Shift (1982), Mr. Mom (1983) and Johnny Dangerously (1984).
