An elderly couple were celebrating their anniversary by dining in a small tavern. The wife leaned over and said, "Do you remember the first time you kissed me over fifty years ago? We went behind this very tavern where we leaned against the fence and you kissed me."
The husband replied, "I remember it well." The wife then said, "Let's do it again, for old times sake." The couple then made their way to the back of the tavern and leaned on the fence.
After forty minutes of passionate kissing and hugging, the couple collapsed on the ground. Catching her breath, the wife said, "Wow. You certainly didn't kiss me like that fifty years ago."
The husband replied, "Fifty years ago that wasn't an electric fence!"
