OK, here's a joke your French friends will hate:
Q) Why are the streets of Paris lined with trees?
A) So the Germans can march in the shade.
Here's another:
Q) Why does the new French Navy have glass-bottom boats?
A) So they can see the old French Navy.
That's it. That's all I've got. I just flew in from Paris, and boy are my arms tired. ;-p
