Jingle Bells,
Batman Smells,
Robin Laid an Egg.
The BatMobile
Lost a Wheel,
And the Joker Got Away!
I like that song
Fun Fact!
Back when me and my brothers used to use Trillian, my brother was talking to my other brother, when my brother would message my other brother (Trillian's chat window would be behind other window(s)) it would always play that song, since that was the set sound, even though my other brother was in his own room while me and my brother were in the living room, i could still hear it :D
