Erich Honecker and the sun

 Erich Honecker wakes up one morning, looks outside, and says "Good morning, comrade sun!"

To his surprise, the sun replies, "Good morning, Comrade Honecker!"

Later that day, he tells some of his colleagues at the State Council Building about it, and they refuse to believe him. So, they go outside, and Honecker calls out, "Good afternoon, comrade sun!"

"Go fuck yourself!" the sun replies.

Honecker is outraged. "How dare you! Do you have any idea who you're talking to?!"

"I'm in the West now, I can say whatever I want!"

A similar version of the joke also exists for Brezhnev.
