I was taking a #2 in the university's main corridor's bathroom, checking twitter when the iPhone froze. I got angry and started pushing all the buttons.

When the phone unfroze, it took a screenshot and made a very loud sound, echoing all over the 10+ stalls.

Someone on another stall said:
- I have no idea what you're taking pictures of. But I surely don't want to know.

More people than I thought were in the bathroom laugh out loud. I sit there for another 10 minutes in shame.
