At a conference on the supernatural, a speaker asked, "Who here has ever seen a ghost?"
Most hands went up.
"And how many of you have had some form of interaction with a ghost?"
About half the hands remained raised.
"Now, how many have had physical contact with a ghost?"
Three hands stayed up, eliciting a slight murmur from the crowd.
"Gosh, that's impressive. Alright, has anyone ever... been intimate with a ghost?"
One hand remained.
The speaker blinked. "Sir, are you saying you've actually had sexual contact with a ghost?"
The man with his hand up suddenly blushed and said, "Oh, I'm sorry. I thought you said 'goat.'"
