Tooth Fairy Update

So, I put a whole dollar under William's pillow last night as he requested. 

This morning, he came running in to my room with his dollar in hand, eyes wide.

William: The tooth fairy came!
Mama: What?
William: The tooth fairy came and left me a whole dollar - that is 100! cents!
Mama: The tooth fairy brought that?
William: YES!  I guess the tooth fairy IS real!

What do you say to that?
