Here we are! Hanne found it for us.
In Russia there lived a man named Rudolf. He and his wife had several children and, one day while getting everyone dressed and out to school, Rudolf mentioned to his wife that it was raining and the kids needed their coats and boots. His wife said to him that he was wrong and it was actually snowing. Rudolf insisted it was raining and his wife insisted it was snowing. This went on for several minutes until Rudolf settled it by looking out the window again, and saying to his wife....
"Rudolf the Red knows rain, dear."
