Instant karma is the concept that you do something that maybe you shouldn't...and get your payback right then. Just ask Robert Meilhammer, who was hunting with some friends when one of them fired at a flock of Canada geese overhead.
As it happened, one of the dead geese fell from the sky and knocked Meilhammer out - and also caused head and facial injuries. It's being reported that he knew who he was, but “little else.”
Meilhammer was last listed in stable condition at a Baltimore hospital.
