Carlton Banks is a fictional character portrayed by Alfonso Ribeiro on the NBC television sitcom The Fresh Prince of Bel-Air from September 1990 to May 1996, the preppy and politically conservative cousin, main foil, and eventual close friend to Will Smith's cool and street-smart lead character. The character has been praised for portraying a complex and sympathetic foil with an arc of personal growth over the course of the show. The character is also known for a dance with humorously exaggerated movements developed for the character by Ribeiro, which came to be known as "The Carlton". Ribeiro also crossed over his role as Carlton into the In the House episode "Dog Catchers" before returning the following season as series regular Dr. Maxwell Stanton for the remainder of that series' run.
