On an overnight flight back from S. America, I was fidgeting around and my wedding ring fell off.
I spent the next 15 minutes using my laptop as a light to try and find it on the floor amidst the feet of sleeping people.
I pulled my seat up (yes, it really can be used as a flotation device) and was a bit panicked.
Then, I remembered that my phone had a flashlight app with a pretty powerful light.
I turned it one and found it under some guys bare foot (yech!).
It had rolled 6 rows back!
Crazy.
