``We're moving on up, to the East Side, to a deee-luxe apartment in the sky ... .'' This spinoff from ``All in the Family'' is about literal upward mobility - African- American couple George and Louise Jefferson move into a swanky high-rise building. George is an obstreperous, often rude guy who thinks his wealth should get him anywhere he wants to go. His wife is more levelheaded and often cuts him down to size when his schemes go awry.
