I've heard a lot of stories like that. My high school French teacher once told us -- in French -- about how she and her husband were on the road somewhere, and she stopped to use the bathroom and ended up going into the wrong one. She got out without anybody seeing her, but the funny thing is, she made the exact same mistake at a different stop on the same trip, and that time she bumped into a guy walking in on her way out.

But I've got a good one too. Disney-MGM Studios in Orlando, Florida. When one makes this error at Disney-MGM Studios in Orlando, Florida, one doesn't lucky and get away without anybody noticing.

I walked amidst probably three dozen people, who were all waiting outside the bathroom for friends or family inside. This waiting area was outside, but the building and an outer wall made a wide corridor of sorts, with benches on both sides, so I merrily sauntered through these three or so dozen people, rounded the bend, and found myself in the women's bathroom, a fact I quickly deduced when I saw five or six actual women at sinks and hand dryers.

I turned around, walked as quickly as I could back through the three dozen people, and made myself scarce.
