The whole point of this ad seems to be that it's howlingly funny that this man:
. . . who is supposed to be, what, Yanomami? Guarani? anyway it's apparently supposed to be hilarious that this guy can speak proper English. This guy who is painted up like an extra from one of the Road movies, speaks like an intelligent, educated person and that's just supposed to funny? How is that not racist?
Who thinks that's funny?
