These lyrics by Stan Kesler and Charlie Feathers always remind me of passwords:

I forgot to remember to forget her,
I can’t seem to get her off my mind.
I thought I’d never miss her,
But I’ve found out somehow
I think about her almost all the time.

Well the day she went away
I made myself a promise
That I’d soon forget we’d ever met.
But something sure is wrong
‘cos I’m so blue and lonely:
I forgot to remember to forget.

Well the day she went away
I made myself a promise
That I’d soon forget we’d ever met.
But something sure is wrong
‘cos I’m so blue and lonely:
I forgot to remember to forget

Or would it be better to compare to 3DES?
