A man with a sheep under his arm walks into the bedroom where his wife is lying on the bed reading. "look darling this is the old cow i have sex with when you have a headache"

His wife answers " You are a right fool if you cant see that is a sheep."
Looking at her he says " and you're a right fool if you didnt realise i was talking to the sheep"

edit : I know a bit sick but .................... Bahhhh :d
