Gilligans Island dropped from 1968 CBS line-up. Bad year. Very bad.

He had been interim president of San Francisco State for less than a week when he climbed onto a sound truck on the campus on Dec. 2, 1968, and ripped the wires from the loudspeaker during a student protest. The event was captured on live television, and the slender, soft-spoken scholar with a fondness for multihued tam-o'-shanters became one of the most popular figures in California. He was dubbed "Samurai Sam."
