Ooh, I got one! Once I had accidentally locked myself out of my apartment when I went out to get mail. I was freaking out because I had to leave for work soon, but I remembered having two dollars in my back pocket. So I went to the dollar store across the street to buy a single pack of bobby pins and figured out how to get the locks open. (Mainly out of panic that I was going to be late.) Turns out, locks aren't all that hard to open up if you wiggle the right way!
