Even though "The LEGO Movie" was snubbed at the Oscars this year for best animated picture, the film's infectious theme song, "Everything is Awesome," was up for best original song.
While performing their hit, Tegan and Sara took advantage of making their appearance extra awesome.
Batman himself appeared on stage with his sidekick Questlove dressed up as the Boy Wonder, Robin.

We hope that was Will Arnett and not just boring old Batman. #Oscars2015 pic.twitter.com/Bqvg7Lmd3y
- Digital Spy (@digitalspy) February 23, 2015Please tell me that's Will Arnett as Batman #Oscars2015 #EverythingIsAwesome
- Moviepilot (@moviepilotnews) February 23, 2015If it wasn't Will Arnett, it sounded just like him. Which means that it might have been the real Batman.
- Empire Magazine (@empiremagazine) February 23, 2015Please tell me Will Arnett is actually in that Batman suit.
- Amy Plitt (@plitter) February 23, 2015I really hope that was Will Arnett in the Batman suit #Oscars2015 #EverythingIsAwesome

- Will Arnett™ (@arnettwill) February 23, 2015Even better? According to "The Lego Movie" director Chris Miller, Arnett was wearing the Batman suit from "Batman Forever."
FUN FACT: @arnettwill was wearing Val Kilmer's Batman suit from Batman Forever. Really. #EverythingIsAwesome #Oscars
- Chris Miller (@chrizmillr) February 23, 2015The Keaton Batman suit was too "delicate" from aging, so obv the next choice was Kilmer
- Chris Miller (@chrizmillr) February 23, 2015The one Val Kilmer wore.
Yeah. Everything is awesome.
