I just had a terrifying experience.
I was putting my pants back on after taking a midday shower, when I began to notice they were really, really tight. Suddenly, and to my horror, from the pants I was struggling to pull on, there rang out a loud ripping noise causing me to gasp in fear. Panicking, I inspected the jeans back-and-front to diagnose how repairable the hole would be. Turned out though, fortunately, that I had simply removed my pants without unzipping them, and the loud noise was my zipper frantically undoing itself so that I might fit into the pants before any real damage was done.
