I remember seeing a kid get warned for stalling for taking someone down and letting them up. The kid did it three or four times in a row, then got dinged all because he "Wasn't working for a pin" (the exact quote from the ref). The kid proceeded to take the other wrestler down, put him on his back and pin him in the next 10 seconds. I'm not quite sure that was what the ref had in mind, but I think the wrestler made his point.
