Moscow Many Moons Ago

A Russian couple were walking down a street in Moscow one night when the man
felt a drop hit his nose.
"I think it's raining," he said to his wife.
"No that felt like snow to me, dear," she replied.
"No I'm sure it was just rain," he said. They were about to have a major
argument about whether it was raining or snowing. Just then, they saw a minor
communist party official walking towards them.
"Let's not fight about it," the man said. "Let's ask Comrade Rudolph whether
its officially raining or snowing." As the man approached the husband said:
"Tell us, Comrade Rudolph, is it raining or snowing?"
"It's raining, of course" he replied and walked on. But the woman insisted.
"I know that felt like snow!"
To which the man quietly said, "Rudolph the Red knows rain, dear."
