I'm sorry, but Mr. Carlson never did any such thing. It NEVER HAPPENED. The Alex P. Keaton on speed episode was excellent, but more because it was off the charts for unintentional comedy. The Saved By The Bell where Jesse was on drugs certainly foreshadowed Elizabeth Berkley's "excellent" performance in "Showgirls." Blossom was just plain terrible and M*A*S*H lost its fastball when Dr. Sidney Whathisname started showing up and shrinking everyone's heads. By the time I stopped watching the Cosby Show, I had been lectured so much I had a Ph. D. in how to suck the joy out of a TV comedy.
