Why did the Frenchman get pissed when he saw someone wiping their mouth with a napkin? He mistook it for his country's flag.
I don't understand, why would a napkin be the French flag?
Because it's white, like the flag for surrendering.
This idea that the French always surrender is insulting. Learn about the many heroic deeds of the French and I think that you will agree this stereotype isn't true.
