Ghosts?

[BRP Tourer]

A country preacher was giving his congregation a sermon on the spirit world, toward the end he asked if anyone had seen a ghost. A small fellow in the back raised his hand. He then asked, " Has anyone ever talked to a ghost?" the same fellow raised his hand. Going further, he asked "Has anyone ever had sex with a ghost?" After a moment the same small fellow again raised his hand. The preacher then said "Sir, I would like to speak with you after the service".
Later, in the preachers office he asked the man to explain how he had sex with a ghost. The man exclaimed, "Ghost!, I thought you said goat!"
