At a conference on the supernatural, one of the speakers asked, “Who here has ever seen a ghost?”
Most of the hands go up.
“And how many of you have had some form of interaction with a ghost?”
About half the hands stay up.
“Okay, now how many of you have had *physical* contact with a ghost?”
Three hands stay up; there’s a slight murmur in the crowd.
“Gosh, that’s pretty good. Okay, have any of you ever, uh…, been intimate with a ghost?”
One hand stays up.
The speaker blinks.
“Gosh, sir, are you telling us that you’ve actually had sexual contact with a ghost?”
The fellow suddenly blushes and says, “Oh, I’m sorry,… I thought you said goat!”
