What's wrong with your horse?
After his beloved horse died, a man wanted to place an ad in the newspaper like this: "Horse saddle and bridle for $50."
Inadvertently, the paper added a comma to the ad, which then read: "Horse, saddle and bridle for $50."
Immediately, someone responded. "That's an awfully cheap price for a horse," said the caller. "What's wrong with your horse?"
"Well, he is dead," replied the man who placed the erroneously typed ad.
