The BIL of a guy I used to hunt with thought it would be a great prank to change the windage setting of my scope while the rifle was in the camp gun rack. I gut shot a deer twice because of that. Good hold on the chest from the kneeling position at about 80 yards, got a decent group - two shots you could cover with your palm, right through the intestines, the second as it started to move. Fortunately I saw the blood on the back half as it ran off and even though I wasn’t sure what was going on gave it a huge hail Mary lead and put one lucky shot in the back part of the lungs so it didn’t get too far.
After I related the tale the BIL admitted what he’d done. Somehow I didn’t see the humor in it. Maybe others would.
