I used the "this isn't a Democracy" line a few weeks ago in a particularly physical contest.
This next one is a softball quip.
Player on a team playing with only 9 players is bi***ing
about balls and strikes and says "C'mon ump, we can't play
11 out here." To which I replied, "would you like to play 8?" That got the usual, "Oh, very funny" comeback from some of his other team-mates, but he didn't say anything the rest of the game.
Oh yeah. The scorekeeper got a kick out of it.
