The keynote speaker at a paranormal conference takes the stage. Before his speech he asks the audience "Please raise your hand if you believe in ghosts". Practically everyone in the audience raises their hand.
"OK, now keep your hand raised if you've actually heard or seen a ghost." Over half the hands go down.
"OK, now keep your hand up if you've touched a ghost." There are only 3 hands still raised at this point.
"Interesting! Have any of you had sex with a ghost?" Only one hand is still in the air.
"You sir! Come up on stage." The man steps forward. "This is fascinating! Please tell us all about your experiences! What is it like to have been so intimate with a ghost?"
The man replies: "Ghosts? I thought you said goats!"
