The Ten Rules Of...
The ten rules of just about anything!  Here you will find many, many rules for just about all aspects of life.  Some of the lists are serious, some satirical, some just funny.   We'll start small and add as we go along.  Many more lists are coming, but here's one to start with:

THE TEN RULES OF BASEBALL:

1.  Praise be to the two run double.
2.  Good pitching beats good hitting.
3.  Go for the long ball
4.  Have a "double play" infield.
5.  Managers don't loose games, players loose games.
6.  If it ain't broke, don't fix it (but bring in a reliever if you must).
7.  If you're on the road, pretend you're at home
8.  Night games are no different that day games, except they're at night.
9.  Good catchers are almost as important as good pitchers.
10. If you can't make the play, you don't get the pay.
