Olympic Stadium, 1976
Bruce Jenner waves the U.S. flag.
After Jenner won the 1976 Olympic decathlon, a fan ran onto the track and handed him a small American flag. Not knowing what to do with it, Jenner waved it, starting a ritual that is now choreographed worldwide. If you agree with Jenner that the routine has grown a little over the top, be thankful that at least there were no Kardashians involved.
