Neville sat under the hat, waiting.

Hello, said the hat, and what would your name be?

Oh no, I forgot!

You couldn't possibly forget your own name, could you?

Yes I can, you wouldn't know, you're just a hat!

Fine. Since you're such a freak, I declare you Hummlenuff! No, Hugglestuff! Great, now your amnesia is spreading to me!

Well, my granny gave me a Remembrall, then we could remember all this stuff!

Good. Now where is this Remembrall?

I forgot.

FAIL. You know, I think we'll be here a while.

10 days later...

Wait!

You remembered?

Yes!

Where is it?

I forgot what I was going to say.

You are a shame. You know that?

No.

'Course, you forgot. OK, better be Gryffindor!

Yay! Hold on, where is the Gryffindor table?
