Daniel Kahneman was being interviewed in his home and was asked whether they gave him a physical price when he won the Nobel Prize in Economics. He said yes, and that he could show it to the interviewer, then went into his bedroom and started looking in drawers, but he couldn't find it (here's the video). "I can't find my Nobel Prize." Awesome.
btw, he has great videos (and writing) on happiness, like this 2 minute video.
