A filmed bit on Saturday Night Live last night promoting Fox’s Empire posed the question: “Empire has already taken black America by storm. But what about white America?” The answer? A “white guy in khakis,” played by host Chris Hemsworth as the new office manager. See him tangle with Kenan Thompson’s Lucious and Leslie Jones’s Porsha on such race-sensitive subjects as signing the office birthday card and filing receipts with your expense report. Once again, Jones saves a flabby, overlong sketch with a few welcome splashes of acid. Agreed?
