Summary of Skit
This is a movie about a man who is Batman, also lives his life aging backwards every year, plus he's Batman.
Announcer: This Christmas, prepare for the cinematic experience of a lifetime.
Doctor: Ma'am, I don't know how to tell you this, but your son has been born an old man who's been aging backwards! (Pulls off sheet.) Also, he's Batman.
(The mom gasps.)
Batman: I'm Batman.
Announcer: THE CURIOUS CASE OF BENJAMIN BATMAN, a touching film about a man who lived his life backwards, and was also Batman. The New York Times says, "Old Batman was sad, Normal Batman was cool, and I guess Baby Batman was cute." (Baby Batman plays with toys, and Normal Batman fights crime.) The Cincinatti Chronicle says, "Maybe he should have been Regular-Aged Batman the whole movie, right?" (Kid Batman fights the Joker.) And the LA Examiner cries, "Why did they make this?!"
Batman: We can never be together, Catwoman, because I'm Batman. (He starts to walk away.) Also, I age backwards. (He starts to walk away again.) Plus, I'm Batman.
Announcer: THE CURIOUS CASE OF BENJAMIN BATMAN. Witness the magic that is the 20 minutes in the middle of this movie where Batman can acutally do stuff!
