A couple celebrates their 30th anniversary by re-walking their first walk together.
They come to the fence against which they first made love.
The husband says, “Come on, for old time’s sake. “
The wife agrees and they both undress.
Afterwards, the husband says, “You’re even better than you were 30 years ago. “
His wife replies, “That fence wasn’t electrified 30 years ago!”
