A guy knocked on my door asking if I had any trees I would like to have cut down (they were "in the neighborhood").
I had one Black Walnut tree in my front yard to cut down.
He didn't say what time they'd be back, and I had to leave for a little while. When I got back and pulled into the driveway, the tree was cut down and the guys were loading the wood into their truck. I got out of my van, tried to have an angry look on my face and walked over to the guy who seemed to be in charge. I said, "that's the wrong tree".
The look on his face was great. I kept a straight face for a few seconds, then I laughed and told him I was just kidding. I don't think he saw the humor in it.
