Have yourself a Merry Little Batman trailer
You better believe Joker sings the all-time banger “Jingle bells, Batman smells” in this trailer

Our only question about the upcoming animated movie Merry Little Batman was: How soon into the trailer will we hear “Jingle bells, Batman smells”? Though we were spared a moody, atmospheric, slowed-down version of the number one banger of all time, the trailer delivers on its promise. The Joker does, in fact, utter the immortal words: “Robin laid an egg.”
We wouldn’t say this version beats the one performed by Robert Goulet, but that doesn’t mean there’s no reason to get excited by Merry Little Batman. From the twisted mind of Regular Show veteran Mike Roth, Merry Little Batman offers a classic Christman conundrum. What if your dad has to work on Christmas and also your dad is Batman? That’s the Yuletide pickle Damien Wayne finds himself in as Dad answers the call of the Justice League, leaving his only son at home to defend Gotham.
