I have the one that I reckon so many people have. I look everywhere for my glasses, search the car, search the house, and these days the wife simply says "Check on top of your head", and 99% of the time they are on top of my head. Worst thing is, last time I checked my head first, nothing there, so starting searching. They were in my pocket. Have now invested in a band for the damned things.
