A psychiatrist is addressing a group of people who have all had experiences with the supernatural. He asks, 'Who here has seen a ghost?' Everyone puts up their hands. He then asks, 'Who here has spoken with a ghost?' Half the audience puts up their hands. 'And who here has touched a ghost?' Ten percent of the crowd puts up their hands. He asks, 'And who here has made love with a ghost?' One small man in the back row puts up his hand! The psychiatrist looks down from the podium at the man and says, 'Do you mean to tell me that you have made love with a ghost?' The small man replies, 'Oh No! I'm sorry. I couldn't hear you back here. I thought you said 'goat'.'
