Worried your single friends may tackle each other in the fight for the bouquet? Why don't you present your bouquet to your mom, grandmother or best friend as a thank you instead?
Another idea is to honor the couple at the wedding who has been married the longest. Have the band leader invite all the married couples to dance and ask them to leave the floor if they've been married for less than 1, 5, 10, 15, 20, 25, 30, 35, 40, 50, 55, 60 years. The last couple standing gets the bouquet, and a round of applause.
