Diff'rent Strokes is a classic American sitcom that follows the lives of two African-American brothers, Arnold and Willis Jackson, from Harlem who are taken in by Philip Drummond, a wealthy white businessman from Manhattan. Drummond had promised his dying housekeeper that he would raise her sons as his own, leading to a significant culture clash as the boys adjust to life in a luxurious Park Avenue penthouse alongside Drummond's daughter, Kimberly. The series is well-remembered for its blend of lighthearted comedy and its willingness to tackle serious social issues, including racism, drug abuse, and child safety. The show became a cultural phenomenon, largely due to the breakout performance of Gary Coleman as the precocious and witty Arnold Jackson, whose catchphrase "Whatcha talkin' 'bout, Willis?" became one of the most iconic lines in television history.
