I'm old enough that when I was a kid I listened to music mostly on vinyl.
When I heard on a sports report that Wayne Gretzky had had a good year in hockey and had "broken several of his own records", I pictured him snapping LPs in half. It seemed like a very strange and destructive way to celebrate a successful athletic career, but I probably figured he was rich enough to buy himself some more records.
