Snape is greasy,

in more then one way,

first is that hair!

I bet he's never cleaned it,

so that's why it's in a fray.

Second is personality,

Oh! It makes me shiver

Just thinking about him

When he's in a temper.

Third is his clothing,

I suppose you could say

It's not quite GREASY

but it's ugly, and there's no way
