Laurence Fishburne (b. 1961) is an actor best known for his roles in Boyz n the Hood (with Cuba Gooding Jr.) and the Matrix trilogy.
He appeared on Sesame Street with Rosita and Telly Monster to demonstrate how one brushes their teeth. Since Telly and Rosita do not have teeth, they plugged their mouths with ears of corn, and brushed those instead.
Fishburne appeared as a regular on CSI: Crime Scene Investigation, while his other television credits have included guest spots on M*A*S*H, Miami Vice, the soap opera One Life to Live, and playing Cowboy Curtis on Pee-Wee's Playhouse.
