DON'T LET IT HAPPEN AGAIN!
You guys will love this story. I'm at a local lawn equipment parts place one day, and their service writer was dealing with a guy with a dead, but new mower that came from a big box store. And apparently, this was his second one. It was locked up. The dipstick was dry. The service writer pointed to the dipstick/filler and asked "Did you put oil in it?", and the guy said, "Yeah, but not in there. In here.", and pointed to the air filter housing"!!!
