My joke is one that I received on Whatsapp from a friend.

An old retired Army Captain had only one favourite hobby and that was fishing. One afternoon while bobbing out at sea in his boat he heard a joice say "hello" Looking around he saw a frog floating on a log. "did you just say hello" he asked. Yes, said the frog, and if you kiss me I will turn into a beautiful woman who will love you and look after you and the world will be jealous. So he lent over picked up the frog and put it in his pocket. I told you to kiss me. "No" said the Captain, I would rather have a talking frog than a nagging wife" - With age comes wisdom Ha Ha
