Yet another reason to take the stairs.
The couple commissioned a comic artists friend of theirs (at http://www.viruscomix.com/subnormality.html) to create a picture of their wedding party. The wedding photographer then had everyone recreate the pose. I think it was done very well.
So the maid of honor and I negotiated this shot with the photographer via silent gestures and nod, right behind the bride's back, on-the-spot during the pictures. It was our one goof move, and the MOH has the classic musical theater "stage moment!" look, while I have my maniacal mad-scientist elementary teacher face on. She had no idea until she got the pictures back!
