From Saturday Night Live's Weekend Update:
Myers: This week, Arizona signed the toughest illegal immigration law in the country which will allow police to demand identification papers from anyone they suspect is in the country illegally. I know there’s some people in Arizona worried that Obama is acting like Hitler, but could we all agree that there’s nothing more Nazi than saying "Show me your papers?" There’s never been a World War II movie that didn’t include the line "show me your papers." It’s their catchphrase. Every time someone says "show me your papers," Hitler’s family gets a residual check. So heads up, Arizona; that’s fascism. I know, I know, it’s a dry fascism, but it’s still fascism.
