What is the dumbest local league rules you have come across?

[tmp44]

Two: 10 and Under league, both involving pitchers:
1) After 4 walks in the inning by the defensive team, there shall be no more walks issued for the remainder of that half-inning.
2) If one pitcher hits two batters with a pitch during the course of the game, that pitcher must be replaced immediately.

The first rule happens fairly often and usually causes the game to only slow down rather than speed up because the team batting cannot score any runs (thus not helping for 10 run rule).

I was doing a playoff game a couple years ago and had #2 happen to the best pitcher Team A had on the first two batters--they ended up getting smoked.
