Actor Malcolm-Jamal Warner, best known for playing Theo Huxtable on "The Cosby Show," has died. TMZ and the Associated Press have reported that Warner died due to an accidental drowning while vacationing in Costa Rica. Warner was swimming at Playa Cocles in Limon province when a current pulled him deeper into the ocean.

Perhaps arguably some of the most iconic Theo moments on The Cosby Show involve him and his friend Cockroach, portrayed by actor Carl Anthony Pane III. For Season 2, Episode 15, Theo and Cockroach have a test on Shakespeare’s Macbeth, and so they decide to read the condensed version rather than the actual assignment.

"The Cosby Show’s" embattled patriarch, Bill Cosby, shared that the untimely death of his co-star, Malcolm-Jamal Warner (Theo Huxtable), reminded him of his own late son’s death, according to a TMZ report.
