The "Ins" and "Outs" of Cricket

You have two sides,
one out in the field and one in.
Each man that's in 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 they are all out, the side that's out
comes in, and the side that's been in goes
out, and tries to get out those coming in.
Sometimes you get men still in and not out.
When both sides have been in and out,
including the not outs, the winner is
declared..... if there is one!
Howzat!
