Bridges
Todd Bridges became addicted to cocaine shortly after the show went off air. Sadly, for a few years he also ran into problems with the law and arrested multiple times. By the late 90’s however, he cleaned up his act and now travels across the United States speaking to various institutes about the dangers of drug addiction.
Round and Round
No kidding, eh, but Gary Coleman frequently appeared in many different television shows in the 80’s, such as The Facts of Life, Silver Spoons, and Amazing Stories.
