The White Shadow - Season 2 Episode 7 Globetrotters

The basketball team is on a winning streak and proceeds to showboat and run up the score on their latest opponent, prompting a tongue-lashing from Reeves. With their newfound success gone to their head, the team gets cocky with the workers at a local car wash and challenges them to a pickup game at the Carver gym. The boys are unaware that the car wash workers are really members of the Harlem Globetrotters doing a benefit and Reeves has arranged for them to show the team they're really not as good as they think.
