A real thing that happened to me. I was wearing a pair of thrift store jeans which I like to buy and in the middle of work the zipper on them came undone. It was like off the tracks and couldn't be used anymore. Whats worse the zipper itself stopped working and came open with no way to fix them (even though I tried like hell awkwardly for like 5 minutes straight). I then just gave up and accepted I was in the middle of work with my tighty whities exposed until I could get home. I tell you I had to do a lot of strategic covering up the rest of that night...
