The French tell Belgian jokes much like Americans tell Polish jokes. But the Belgians take their revenge once in awhile.

How do the French commit suicide? They point a pistol 15 cm above their head and shoot point blank into their superiority complex.

What's the difference between Nelson Mandela and a French politician? Nelson Mandela served his prison sentence before being elected.

The Nelson Mandela comparisson is entirely appropriate for US politicians as well.

Having lived in Florennes, Belgium, a year, I can attest to the French jokes they develop. Here's one:
Why is the Champes D'Elaise in Paris lined with trees? The German army likes to march in the shade!

Brings to mind the old joke about being able to tell one's nationality by how the person acts upon entering a bar: An Englishman walks in, looks around and sizes it up as though he wonders who owns the place; A Frenchman walks in with the air of one who does own the place and the American bursts in, sits down and loudly orders a drink because he gives not a damn who owns the place!
Too true, too true.
