AACS key on a check

Hobie just ordered new checks and needed to put something useful in the address field, so he added in the notorious AACS key! This is the storied integer that is used to break the copy-control system in HD-DVDs. The AACS licensing authority says that distributing this number is a crime. That's not working: 1.5 million pages on the Internet contain the key today.

(Thanks, Hobie!)
