There's a Viking called Rudolf the Red, on account of his hair and beard. One day, he comes in soaked to the skin and declares to his wife, "By Odin, it's pouring out there!"
His wife looks out of the window and says, "It's worse than that, it's snowing heavily!"
"No, it isn't, it's just raining hard," says Rudolf.
The wife looks out again. "I'm sure it's snowing," she says.
Rudolf sighs with exasperation and tells her, "Rudolf the Red knows rain, dear!"
