Overheard in East Germany

Jokes are a window into the truth, and Germany has released some of the jokes West German intelligence overheard in East Germany during the Cold War:

Did East Germans originate from apes? Impossible. Apes could never have survived on just two bananas a year.
What would happen if the desert became communist? Nothing for a while, and then there would be a sand shortage.
Why does West Germany have a higher standard of living than we do? Because communists can't get work permits there.
A new Trabi [one of the planet's most god-awful cars, and pride of the GDR] has been launched with two exhaust pipes -- so you can use it as a wheelbarrow.

What do our jokes say about us?
