As he boarded his venerable longship, the mighty Viking warrior, Rudolph the Red, readied his sturdy craft to sail the turbulent waters of the North Sea. Once again, the fierce leader and his men would reign terror over the poor, unsuspecting villagers of the British Isles as the Vikings pillaged their way through farms and fields of Scotland and England.
As the crew completed their final preparations for the perilous voyage, the rugged chieftain leaned over the bulwark of his vessel to kiss his wife goodbye, and he said to her, "Tomorrow, we shall be victorious in battle. But today, we sail forth into a storm."
As she cast her gaze toward the sun as it slowly rose above a clear horizon, she asked her husband, "How can you be so sure?"
"Because," he replied, "Rudolph the Red knows rain, dear."
I will admit that I saw the punch line from this brief bit of humor several years ago, and I chuckled when I read it. However, I couldn't find the source of the original pun, so I decided to write my own story, albeit with some AI-generated artwork. This illustration of Rudolph the Red was generated by the application at http://bing.com/images/create, where I asked it to create "a 3d image of a viking with red hair on a ship that is sailing through the rain." I think the image fit my story rather well.
