Trivially defeated with a boot disk and ResEdit.

Breaking things with ResEdit was pretty much my jr. high school hobby. It took a bit before I figured out how to restore things when I was done.

Head "tech" guy in the building eventually figured out it was me, showed me a few things and ended up just giving me an un-limited login and a few rules. Also taught me how to intelligently use ResEdit instead of the brute-force method(s) I was used to.

You didn't even need a boot disk and ResEdit. Just hold down the Shift key while the Mac was booting from the hard drive, and system extensions including Foolproof would be disabled.
