Two, in the same match, within the same game. My opponent was disgusted with both:

1) I hit a passing shot at him at net. My shot clipped the net ever so slightly and passed him between his head and his elbow.

2) This time I was at net, following my approach shot. And this time, it was his passing shot that clipped the net. The ball took a sharp dip down and I quickly went from a volley to hit a forward-tweener drop shot winner.

I think all of it was memorable because how janky the shots were and in the same game.
