Two Polish guys are discussing one's upcoming wedding... "I'm not sure if
my future bride is a virgin or not."
His buddy replies, "Oh, there's an easy test for that.  All you need is
some red paint, some blue paint and a shovel.  You paint one ball red and
one ball blue.  On your honeymoon, if she laughs and says 'Those are
the funniest balls I've ever seen!' you hit her with the shovel!"
