I love your #2 (hmmm....sounds kinda funny).

Had a SP game one time where a batter made a mark on the ground right behind home plate just after I had called a strike. When I asked him what was that, he replied, "That's where the ball landed."

I went to the front of the plate (like I was going to brush off the plate) and waved my hand in a circular motion right above home plate, waist high.

When he asked me what did I just do, I replied, "That's where the ball crossed the plate. Any questions?"

Never heard a peep out of him the rest of the night.

Yup, gotta love it.,
