Well, to get back to your original question, what if Simon is a Ravenclaw and the chip is a Hufflepuff? Or the other way around? (I do suffer greatly from anthropomorphic tendencies, if you couldn't tell.)

Miles and the Hat would be a great name for a band. (somehow I think Ivan would be outvoted in the naming process)

Not sure I want to know what happens if the hat and the chip get together.
