A Breton tourist whose car is number plate end by 22 (Côte d´Armor) is on vacation in Marseille.
He drives down Boulevard d'Athènes to reach the Vieux Port. It's 2pm and as usual, it's a big traffic jam. In front of the Breton’s car is that of a Grandpa from Marseille.
The Grandpa constantly changes lanes, first to the right, then to the left, then to the right and so on.
Ulcerated, the Breton gets angry and finally manages to overtake him. Arrived at the height of the Grandpa, he leans towards his right window and yells: "So old man, you stop changing lanes all the time!" We drive on the right, that's all! "
The brave Grandpa, who has his window open, looks at the Breton with a completely astonished air and answers him: "Oh fada! Here we are in MARSEILLE! We drive neither on the right nor on the left! "
The Breton driver couldn't believe his ears and went on: "Oh good! And where do you drive in MARSEILLE? "
The Grandpa retorts: "Hey, as usual asshole, we drive in the shade! "
