Heh -- good start, there.
I really DON'T speak French, so this is the best I can do, allowing for some idiomatic English not reflected in the original:
A bus was carrying politicians to Congress. The bus went off the road and crashed in a field belonging to a farmer. The farmer, after seeing what had taken place, took a look at the crash site. He began to dig a ditch and bury the politicians.
After he had finished, the local sheriff drove by, saw the crashed bus, and asked the farmer what had happened to the politicians. The farmer said he had buried them all. The sheriff asked the farmer, "So then they were ALL dead?"
The farmer replied, "Well, some of them argued that they were still alive, but you know how politicians lie."
