I Asked 64,182 People About “Jingle Bells, Batman Smells”. Here's What I Found Out. by Tom Scott

This video provided a lot of laughs for us last night. My personal recollection of of the song is:

Jingle bells, Batman smells,
Robin laid an egg,
The Batmobile lost a wheel,
And the Joker got away... hey!

I even owned a t-shirt that was based on this version of the song.
