Drop kick

Similar topic, different reaction. Kick a ball, fun. Kick in the balls, pain - but only for people, not dogs. Another example in the series where circumstantially it's better to be the dog. Also dogs don't laugh if a fellow pup gets kicked there. People laugh. It's funny, not Soupy Sales humor, but the classic burst of laughter reaction, kind of like jumping when scared or flinching at a popped balloon. For a dictionary definition of the phrase kicked in the balls please see the prosecutors of Casey Anthony.
