Funny, I read that as the title of an epic poem in blank verse by the 17th-century English poet John Milton. I suppose not having their password could be why they couldn't get back into Eden.
Of course had Adam and Eve simply provided themselves with another account that was sudoable, they might've used that password to get to some more apples. Failing such a easy solution to their dilemma, mounting the sdcard in another machine and chrooting in might help. The problem though is that people often want to do this on a machine that isn't arm, like their x86 laptop, which won't directly work. You can, however, mount the sdcard and make changes by editing files, perhaps to include booting to single user mode allowing access to root without a password.
Although few people seem inclined, I think that getting a second sdcard, any size at all should be fine, and putting on a memory only linux distribution, e.g. tiny core, booting to that, removing it and mounting the sdcard with the issue and then chrooting to that, doing all that is a good idea. What this should allow you to do is get root and run any reasonable command line program you want, although you probably can't run anything X because tiny core and R. jessie have important differences, I think it's not having systemd stuff and having it that is that problem.
