Let's all join in a chorus of "Hippo Birdie Two Ewes" to your favorite Potions Master and mine, Severus Snape! Even JKR honored this day at her web site, which Leaky so nicely supplied a link to. If he were alive today he would be 48. Gee, can you believe it will have been ten years this coming May that he's been gone? Wow, it seems like I found out about it just last July. Wait... I did!  So cheers to that great swooping, sweeping, dark prince of the dungeon. He will always have my heart. I'd happily jump out of a cauldron for him!!

 
"In the name of Merlin, stop singing that insipid song. Is it not enough that I'm already dead? 
Must you torment me further?"
