One could generalize from their success to teach a
cognitive discipline of passphrases which are more
memorable than alphanumeric gibberish but less obvious
than these old standbys.

Perhaps a challenge, then, would be to tell a top
level systems administrator at a large financial
insititution how to craft a passphrase formula that
would be memorable, unique and generative of
passphrases for, say, 100 critical services which
should not share a single passphrase.
Naturally, a bit of "history" is lurking in the above.
