Met Him in Hawaii

This was about ten years ago, but my mom and I ran into Henry Winkler at a shopping mall in Hawaii. He stopped and talked to us for a bit, and was a very nice guy. When I admitted I didn't know who he was (I was about 9), he playfully did his signature Fonz, "Eyyy" for us. He was very down-to-earth... I guess that's why I didn't realize how famous he was!
