Am I the only one who's sick of these lame-ass repetitive jokes? They even lifted a bit straight off of Jon Stewart.
Back in the War years, it was Japanese (but really any non-Middle Eastern or Indian looking person from Asia), Germans, and Italians who were "totally acceptable" targets, then it was the Russians and Chinese (again, really anybody from East of Burma), and now it's the Irish, Canadians, French, Americans (funny enough), and still East Asians.
This was not funny, nor has it been the 95 other times I've heard the exact same bits.
