Similar except that the playing board was to be the ass of one of the players and the idea was to set up beer cans on it and try to knock them down with some kind of missle.

It was going to be call:  Bust My Hump.

Another version would consist of a contest to gather as many nuts as possible while your opponent uses a nut cracker to open them up before your done.

To be called:  Bust My Nuts.

The playing board was a tray of uncooked brownies that you place into the oven once all the nuts were broken.

I planned to market it to Boy Scout troops who like to eat Brownies.

I've got to go watch the Beaver right now.  Ta-ta.

No, no double-entendres here.  Ball-buster just means "working somebody hard," and hell, men don't even have balls, and if they do, they're not called balls anyway, they're called . . . you don't know whats.
