We are doing something like this. All the married couples will start to dance on the floor. The DJ will start eliminating couples based on time married. New hubby and I will be first to leave, followed by the next shortest marriage, etc., until the couple married the longest is left standing. I'll then give them a special bouquet (or something). That will be in place of the bouquet and garter toss.
If I am correct, I believe it is where all the couples stand up to dance and as the song goes on the DJ will announce years that the couple is married. You stop dancing with your partner once it no longer applies to you. The couple married the longest is the last up there and the bride sometimes gives them the bouquet. I think it is sweet but am opting not to do it due to my grandma who recently had my grandpa pass and they would have probably been married the longest. Don't want anyone to be sad.
We know who the longest married couple is at our wedding. Their 55th wedding anniversary is on our wedding day. We will have our first dance and then have the Dj announce their special anniversary and we will dance to Don't Blink by Kenny Chesney. I will give my bouquet to her and my new hubby will give a nice bottle of scotch to him. No bouquet/garter throw.
They take forever and everyone pretty much knows who will eventually win; i.e. the bride's grandparents, or someone like that. It gives us young couples time to head to the bar or the bathrooms.
We didn't do one, which should be no surprise. My grandmother would have cried through the whole thing, even though my grandfather had passed years before. They loved to dance, took professional lessons, and belonged to a dance club. Instead I gave her my bouquet and she took the long stems out, to put on my grandfather's grave and kept the shorter stems.
