They are funny !  Les Têtes à claque was created by a group of Quebecers and in order to understand it you need to know the ''Quebecers slang'' which we call here ''le Jouale''. They have been running for the past year and a half through the net, radio and TV stations all across the province of Québec. Even someone from France would not understand it because it is a 'cultural thing' tipically Quebecer.
Since I've been living for several years in Montréal, I can understand their slang. It is quite something to see them having fun like that. Some of the caracters reminds me the face of Jean Chrétien with his funny manners.
