Alright, you're either Jewish, have Jewish friends, or do excellent research, because I have NEVER seen the villain of the Purim story referenced in any form of media not directly about the holiday. Ten points to Ravenclaw.

I've got Jewish friends, ayup. Plus, well, I read a lot of 19th century literature growing up--"Hang him higher than Haman" was almost a cliché, at one time.
Thank you very much!!
