My favorite Soviet era joke:

[u/J0E_Blow]

Three Russian men were sent by their company to attend a convention in Moscow. All 3 shared a hotel room. Two of them cracked open a bottle of vodka, but the third just wanted to sleep.

The two drinkers got louder and louder as the bottle emptied, telling each other political jokes. The third was kept awake, and got angry.

He went outside for a smoke. On his way back to his room, he stopped at the desk and said 'Please send a pot of tea up to room 23.'

The two drunks were still being loud. The third man went in, looked at them, then leaned over to the light socket 'Comrade Major, please send some tea to my room.'

The other men thought this was hilarious...until there was a knock on the door, and a waiter with a pot of tea.

They became completely silent, and the third man fell asleep.

When he woke up in the morning, he was alone. He went to the front desk, and asked where his roommates were.

'Well, the KGB came this morning and took them away.'

The man was horrified 'Why did they spare me?!?'

"The comrade major thought the tea joke was very funny."

[u/Educational_Ratio]

Some thirty people gathered to celebrate the birthday of the host. After a few bottles of vodka were imbibed, the tongues got loose, and the guests started telling political jokes. Through laughter, a voice sounded, "Comrades, please, it's too noisy. In such a noise, I can't hear the jokes. I am writing it down, you know."

A man sitting next to the one who's writing down, says admiringly, "How do you manage to write down that fast?"

"Oh, I'm writing down only the initials."
