Sergey,

>In this case there should be also "Surprise me" button in addition to Exit, and Don't Exit. :)

I can't resist. I am going to put one or two of these deep in an application where they will almost never be found. Have the "Surprise me' button do something harmless that hopefully is not offensive in whatever culture the user lives in, and then return to the real choice that needs to be made.

Thanks Sergey, you made me laugh.
