Basketball fans got a special treat at a game between the LA Lakers and the New Orleans Pelicans on Wednesday.
Ferrell can be seen lining up to take a centre-court shot at half-time, but "accidentally" nails a cheerleader right in the face with the ball.
He was then "escorted" off the premises by other actors.
