I took this photo at Trocadero in Paris.
Just before I took this shot, my wife was wondering "where did my husband disappear to now", and all of a sudden she looked up and saw me on top of this ledge getting ready to take this shot, and burst into laughter. As you can see below (first comment), she took a photo of me taking the shot, to show me how silly I looked!
