My wife's parents celebrated their 40th wedding anniversary last weekend and we had a small luau BBQ in celebration.  They were married while John was on leave about to go to Vietnam and put their wedding together in a week.  They really are an inspiration in the way the care for each other and how great of parents they are.  My wife made them a banana cake, which is what they had for their wedding!

They commemorated with a frosting fight.  I'll spare you the images of my FIL trying to lick Judy with his cake-covered tongue!
