1. What francophobes call Le Grande-armee.
2. What France hasn't done in a while.
3. Something that hasn't happened in a very long time.
Napoleon's Frogmarch soundly defeated armies from Russia and Austria at the Battle of Austerlitz.

Germany has invaded France again, they've taken Chirac prisoner, and are currently busy rebuilding the Bastille and melting down the Eiffel Tower for ammo! Looks like time for a Frogmarch!

Our Government's being honest to the people?! That's a Frogmarch!

FOOTNOTE: This is a joke; I don not hate or scorn the French (though I can understand why some people do), and I do not call the French "Frogs" in everyday life. If you care to read my honest view on France and its people, go to (French).
