What do you think is the dumbest rule?

[TXMATTHEW05]

Hello, all. I was wondering, what do you think the dumbest rule in basketball is?

First, administrative technicals for something like the starters not being marked. I can understand incorrect numbers and such (even though most would agree that 99% of the time it's just error, not deceiet). For the life of me, I cannot figure out what difference it makes. When I do the books, I don't even mark who goes in afterwards, because that sort of information is irrelevant, really. The only purpose I can see would be to confirm that the number is in the book, but I double check during the pre-game. I just don't get it. It's a dumb rule.

What do you all think?
