HAHAHA...I tried this Outrageous Names generator, from Blogthings again, for fun.

Hooooooo = Lucy Bowels = Hope Chow...which is spooky.

Anyway, then I tried severus Snape (yes, like that, I forgot the capital S in front) and....Harry Muff?! Severus Snape= Hugh Mungous, which sounds like Harry+Mundungus.
Harry Potter= Mike Hawk (ha!)
Remus Lupin= Craven Morehead (D.O.T.S...)
Tom Riddle= CRAVEN MOREHEAD.
Eek!

Gao, you won't like this.
Ron Weasley= Guy Nuhcologist

Nymphadora Tonks= Mary Wanna. Apparently Tonks sounds like a drug name. I am puzzled.
Alastor Moody= Hugh Jass (*dies of laughter*) I tried again and got Harry Muff.

Bellatrix Black= Amanda Gollick (it sounds wrong)
hahaa..
