oh, the temptation

I'm reviewing some documentation I wrote back when I first joined this company, to see if it's still accurate. I encountered the following statement (in a situation where A logically must be greater than B):

"[class] does no checking of these two values; if you set [A] to be less than [B], the results are undefined."

What I really want to write instead is: "if..., you will deserve what you get, and don't call us for support".

But that would be unprofessional. Shucks. :-)
