There once was an old communist in Russia whose name was Rudolph Barichnikov.
He was standing in his house one day with his wife. He looked out the window and saw something happening. He says to his wife, "Look honey. It's raining."
She, being the obstinate type, responded," I don't think so, honey. I think it's snowing."
But Rudolph knew better. So he says to his wife," Let's step outside and we'll find out."
Lo and behold, they step outside and discover it was in fact rain.
Rudolph's wife turned to him and asked "How did you know it was rain, honey?"
And Rudolph turns to his wife and replies, "Rudolph the Red knows rain, dear!"
