Hello. I'm Sirius Black, and am much, much, sexier than silly Remus Lupin, and definitely sexier than James Potter. And, really, don't even bother comparing my sexiness to Peter Pettigrew, because, well.
Once in a while, I'm a very sexy black dog.
And Snivellus Snape is a bastard, a prat, and a generally very annoying person. Just so you're aware.
