There would be no ball, you'd need to look for it for ever by solving cryptic clues on sticky notes placed on some of the 4 billion spectator seats which all look same....but with brilliant detail
While you search you can trim the lawn, you can use mowers, clippers, razors, or even a pocket knife, but you can also group up and mow together with your friends, sometimes there will be pirates though that will try and steal your grass clippings.....
As a bonus you can sell the grass, or sell the smoking kind on a black market so that you can get a bigger mower, or maybe a stick with a nail in it from a seedy bald mechanic so that you can chase those pesky rogue mowers away.
sounds like you've been smoking lol
