There was a very funny joke at the times in the french satirical puppet show "Les Guignols de l'info".
During the joke, an US official stated "we have proof the Iraqi have chemical weapons, look at those documents here, they ordered those weapons from us, and we delivered a few years ago"
Then a second official interrupted him saying "Stop the invasion, we are making a terrible mistake"
"What, they don't have chemical weapons ?" asked the first official
The second official answered : "sure they have the weapons, but they purchased on credit and have 12 monthly payments left to make, so we can't invade them now"
