Here's another little piece of fan art based on a song parody. This time the song is Jingle Bells, and that parody was first heard on The Simpsons' Christmas Special. The people at Warner Brothers Animation liked it so much, they decided to include it in the Batman: the Animated Series episode "Christmas With The Joker".
Hope you like this as much as they did, and Merry Christmas/Happy Holidays to all!
