Haha...this was a kid who was only on his second day of classes with us. He had never sparred before and I told him that the goal was to hit his partner (lightly) - I told him to try anything that he thought would work.
After this shining moment, we tried more conventional things like looking for open targets, throwing combinations, etc.
Had this been a long-term student, it would have definitely been a "grrr" moment for me (and a jumping jacks moment for the student)
