In the first episode of ABC’s “Fresh Off the Boat, a new fish-out-of-water sitcom about a Taiwanese-American family that moves from DC to suburban Orlando, patriarch Louis Huang (Randall Park) floats the idea of hiring a white greeter for the steakhouse he owns so white people will feel comfortable when they walk in and spot a familiar face. It’s a clueless, optimistic line that is played for laughs, and Park’s delivery is laugh-out-loud funny.
