A wonderful resource: Soviet political jokes, translated into English. Here's one:

When Nixon visited the USSR, Brezhnev showed him a Soviet phone of the latest technology in which it was possible to call Hell. Nixon called the Devil. The conversation cost only 27 Kopecks.

Upon returning to America, Nixon told everyone about the Soviet marvel. But as it turned out such a phone had been invented in America a long time ago. Nixon again called Hell, but this time the conversation cost 12 thousand dollars!

Nixon, understandedly upset, cried, 'But in the USSR a phone call to Hell costs only 27 kopecks!'

'Yes sir, but there it was a local call.'

And one more:

A person is walking along the street in one boot.

'Have you lost a boot?' a passer-by asks.

'On the contrary - I've found one!'
