A man and his wife were on a road trip to visit their families for the holidays. They had been driving for hours, and both were getting a bit restless. Suddenly, the man had an idea.
As the man and his wife were driving on their road trip, they passed a field full of cows. The man turned to his wife and said, “Did you know that cows can sleep standing up?” His wife replied, “Really? How do you know that?” The man replied, “Well, I used to be a farmer, so I know a thing or two about cows.”
A few miles down the road, they passed another field full of cows. The wife pointed to one of the cows lying down and said, “Looks like that cow didn’t get the memo about sleeping standing up!” The man chuckled and said, “Well, that cow must be a horse in disguise!”
