I was listening to a short story that I found on my friend's itunes playlist this week. It was called "The Dybuuk in the Bottle". It was a fun little story about an asshole demon that an amateur rabi finds in a bottle near his house and attempts to have the demon do his bidding. However, the Demon makes his living situation rather frustrating so the amateur rabi guy asks an awesome rabi guy to help him get rid of the demon that has taken over his house. The awesome rabi guy assumes ownership of the house and from there is able to beat the demon at his own game. The amateur rabi guy learns a valuable life lesson and gets his home back.
Anyhow, this the what I thought the demon looked like.
