A couple are walking through St Petersburg Square on Christmas Eve
They feel a slight precipitation.
The man says, "I think it's raining."
His wife disagrees, "No, it's snowing!"
Unable to agree, the man says, "why don't we ask the nice Communist officer over here? He's always right! Officer Rudolf, is it raining or snowing?"
"Definitely raining," said the officer before walking off.
"See?" the husband says, "Rudolf the Red knows rain, dear."
