Few celebrities in 1980s were as outspokenly against drug use than Mr. T - who turns 64 today. The muscular actor known for playing antagonist Clubber Lang in Rocky III (1982) and B.A. Baracus on TV's The A Team (1983-1987) lent his imposing frame to confronting kids about the perils of using marijuana and other substances.

Mr. T - whose real name is Lawrence Tureaud - starred in anti-drug PSA's on TV, promoted the Just Say No campaign and released the funk rap track No Dope, No Drugs. And he was specially recruited into America's drug war by none other than former First Lady Nancy Reagan. When the "Just Say No" founder died March 6, 2016, Mr. T went on Twitter to offer a touching tribute to her and their work together.

While we don't always agree with the actor's methods, or the "Just Say No" campaign's approach," there's no denying that his heart was in the right place when he helped Reagan keep marijuana and other substances away from kids. The two also collaborated on one of the strangest White House photos ever. When they met in December 1983, Mr. T arrived as Santa Claus and the first lady sat on his lap. Seriously.
