context: We have a large yard, a half acre on a corner lot. Due to the size, we have a ride-on mower which makes cutting the grass relatively easy, I would even say "fun." Thanks to a lot of experience, I can get that thing moving and get the yard done in just a little under an hour. It's normal, average, boring. Except this one time.... A cousin had taken our ride-on mower to do some maintenance on it. He had taken it on a Friday evening and had promised it would be back by Sunday evening. He was wrong. Sunday and Monday came and went with no sign of our lawn mower. Tuesday evening came and the grass was up to your ankles. It needed to be cut. We had bought a small push mower to get into the small spaces so we pulled it out. Me, my wife and my mother-in-law took turns pushing that mower up and down the yard for a good two hours. We had one tiny little bit left of the yard when Howard, the cousin, pulled up with the push mower.
question: Who mowed the grass?
reference: The speaker, his wife and mother-in-law
candidate: everyone.
