Lee Holmes (a developer over in the Monad group) had a problem.
It seems that he had an application that just insisted on his being an admin to work correctly...
Being a blogger, of course he wrote about it: here.
I don't recommend anyone doing this, but it's an interesting approach to fixing a broken application.
And yeah, I know that if the application was open source, it wouldn't have been a problem. Just don't go there :)
