Baseball

My Grandma (a great supporter of little league and a baseball fan) has this simple explaination of the game on the spare bedroom wall (for the uninitiated).

Baseball
You have two sides: one out in the field and one in.
Each man that's on the side that's in goes out and
when he's out he comes in and the next man
goes in until he's out.
When three men are out, the side that's out comes in
and the side that's been in goes out and tries to
get those coming in out.
Sometimes you get men still in and not out.
When both sides have been in and out nine times
including the not outs, that's the end of the game.
