1) There's no limit on pitches - you swing until you hit the ball
2) After you hit the ball, you must jump in and swim to the other side of the pool (1st base)
3) Since Mommy never wants to get her hair wet, it takes her too long to retrieve the ball and make it to the batter to tag them out (therefore, everyone is safe on 1st)
4) You must "steal" 2nd base while Mommy "isn't looking"
5) You must "steal" 3rd and home as well
6) Mommy must be a bad infielder
7) It's more fun when Daddy plays pitcher because he gets it in the strike zone more often than Mommy does
