I was watching the Marlins/Braves game yesterday. Preston Wilson was on 1st and getting his lead, and he ran back to 1st on the pick-off attempt. The announcer then mentioned that he didn't tag 1st, which is required by the rule book. Only catch is, there is NO PENALTY for breaking this rule. this struck the announcers and me as kind of odd. What the hell is the point of having a rule if there is no penalty for breaking it? So are there any rules like that in baseball or other sports that strike you as strange, outdated, obsolete, etc.?

The one in basketball where they have to get the ball thru the net to score.

International Canoe Federation of Slalom Racing states that a competitor must be male or female. What about hermaphrodites like ladi?
