Cosby - Season 1 Episode 14 Guess Whose President is Coming to Dinner?

In a White House public relations move, Hilton is chosen as the ideal ""common man"" to dine with the president. When Hilton calls in to a radio talk-show, the president's deputy communications director hears him and tracks him down to ask him if his family would like to have dinner with the president--on a date that conflicts with Ruth's plans for a relaxing weekend in the Poconos. As the Lucases get their home in tip-top shape for the visit, the media converges on them, and Pauline, Griffin, Singh and New York Mayor Rudolph Giuliani try to convince Hilton that, as ""extended family,"" they really should be included in the evening's festivities.
