Over the weekend, Olympic swimmer Matt Grevers invited his girlfriend onto the winner's stand after he won the 100-meter race at the Missouri Grand Prix, got down on one knee, and proposed. Apparently his original plan was to propose to Annie Chandler after she won her race but unfortunately, she came in 5th place. I'd say it turned out pretty okay.
