Investigations of a Dog Puns

a man, a sheep and a dog are the only survivors of a shipwreck and get marooned on a desert island with more than enough food. days, weeks and months pass and the only thing the can look forward to on the island everyday is the beautiful sunset! every evening the man, the sheep and the dog go and watch the sunset... one day the man attempted to put his arm around the sheep and the dog goes crazy so he has to retract his arm. he angrily exclaims "I was just cuddling!" the next evening they are back on the beach and the man sees something out to sea... after further investigation he sees it is a unconscious woman on a raft! the man swims out and rescues the woman, takes her to shore and nurses her back to health they begin chatting and get on incredibly well, she was a beautiful young woman with a great sense of humour. the next evening the man, the woman, the sheep and the dog go to the beach to watch the sunset as per usual... whilst sitting on the beach the woman looked up at the man, and he looked back at her. she says how can I ever repay you? the man then says "you can you take the dog for a walk?"
