Rudolph the Great

There once was a czar in Russia whose name was Rudolph the Great. He was standing in his house one day with his wife. He looked out the window and saw something happening. He said to his wife, "Look, my dear, it is raining."

His wife was very obstinate and responded as follows: "I don't think so, dear. I think it's snowing."

But Rudolph knew better. So he said to his wife, "Let's step outside and we shall find out."

They both went outside to discover that it was raining. Rudolph, very proud of himself, turned to his wife and said, "I just knew it was raining because, Rudolph the Red knows rain dear!"
