In my role of Wedding DJ/MC Johnny Only, I am often asked to celebrate marital longevity by doing an “Anniversary Elimination Dance.” This is a slow dance just for married couples.
As the song progresses, I have people that have been married for a certain number of years sit down while the couples that have been married longer remain dancing.
I keep raising the number until there is only one couple (the longest married) left on the dance-floor. Sometimes the bride and groom offer them a flower(s) but every time,
I ask longest married couple to share their secret of wedded bliss with the newlyweds.

The best answer I ever heard was that, “A happy marriage is like a homemade casserole; Only the people that make it really know what goes into it.”
