Economists In Parades
There is also a joke about the last Mayday parade in the Soviet Union.
After the tanks and the troops and the planes and the missiles rolled by there came ten men dressed in black.
"Are they Spies?" Asked Gorby?
"They are economists," replies the KGB director, "imagine the havoc they will wreak when we set them loose on the Americans"
