Two hunters are traipsing through the woods when they happen upon a clearing. Standing in the center of the clearing is a 20 year old blonde with no clothes on.
First hunter asks, "Ma'am, are you game?"
Flashing a knee-buckling come hither look, she replies, "I sure am boys!"
So the second one shot her.
(For non-English speakers, 'game' is prey and also a colloquial way of indicating willingness to do or participate in something.)
