[pen] I doubt if one blithering idiot is more likely to be of use to the nation than another in an emergency. Thanks for bringing the news to my attention though - I didn't know anything about it till now.

[Phil] One example in standard English occurs to me: to black (a pair of boots, or a place of work).

Similarly, "to right something" and perhaps also (less clear) "to wrong someone"?

[Raak/CdM] However, "black" is also a noun. So is "wrong" and "right." Can an example be found which verbs an adjective which is not also a noun?

I was going to point out that "to up prices" involves verbing a preposition, but "up" can yet again be used as a noun.
