87th Annual Academy Awards - ShowOne of the more enjoyable surprises during the incredible "Everything Is Awesome" performance at the Oscars (quick question though: how was there not confetti canons of some kind?) was when Will Arnett showed up as the Dark Knight himself to do a bit of his Batman song from "The Lego Movie." It was hilarious and insane and it actually had a bit of history behind it.

As "The Lego Movie" co-director Chris Miller tweeted shortly after the performance, Arnett was wearing the Batsuit worn by Val Kilmer in "Batman Forever." And this is 100% true. It was almost unnoticeable, though, because Arnett's performance (with an assist from Questlove) went by so fast and because his suit was augmented by a Lego bat logo.
