Boggart

I think that when the Boggart is alone, it's shape is what _it_ fears 
most. And what does a boggart fear most? Laughter (because that's 
what defeats it!). So, I'd assume it's true form is clown or 
something... but I do think Moody knows how boggart's look like! Not 
only by seeing a boggart INSIDE the cupboard, but also by seeing 
trough it's attempt of deception...
