more out of date jokes

Mr.Gopher pointed me toward a similar style of East German jokes from Radio Eriwan.
here loosely translated by myself:

Could the catastrophe at Chernobyl have been avoided?
Sure, if the Swedes hadn't blabbed about it.


What is Chaos?
Questions about the State Economy will not be tolerated!


Can you clarify the difference between Democracy and the People's Democracy?
Sure. It's like the difference between a jacket and a straitjacket.

Of course, there are a couple I don't understand, or that just wouldn't be as funny in English, because the play on words only works in German. e.g. another joke about Chernobyl mushrooms & toilets. I don't get it. Maybe it's better that way.
Can you drive 120 km/hr [70 mph] in a Russian car on Russian streets?
Sure. Once.


Can we spread Socialism to Canada?
Sure, but then who would produce all our wheat?


Can we spread Socialism to Switzerland?
Sure, but it would be a shame do that to such a nice country.
