Well, the Poles have their own jokes about the rest of us humans, and the ones I've heard are pretty funny:

Q. What is the purpose of the USSR?
A. It is a buffer state between Poland and China.

Q. If Russia and Germany once again attacked Poland, which front would you choose to fight on?
A. The eastern front. Business before pleasure.

The USSR built a monument to Chopin, so of course the Polish ambassador was invited to the unveiling. When the drape is lifted, it reveals a sculpture of a man with a little pointy beard. The ambassador leans over to the man next to him and whispers, "But this is not Chopin!" "Of course not!" replies the Russian, "It is Lenin *listening* to Chopin."

When Napoleon marched on Moscow, he wore a red shirt, so that in case he was wounded, his soldiers would not notice. When Hitler marched on Moscow, he wore brown pants.
