‘Don Knotts: Tied Up with Laughter’ DVD unearths vintage ‘Hollywood Palace’ skits

“Don Knotts: Tied Up with Laughter” collects the rubber-faced comedian’s 1970 episode hosting “The Hollywood Palace” musical variety series as well as bonus material including the hysterical nervous master of ceremonies routine.

Don Knotts remains a beloved comic genius who sculpted two characters still heavily seen in reruns — the child-like, emotion-on-his-sleeve “Barney Fife” on The Andy Griffith Show and the loudly dressed, perpetually confused Ralph Furley on Three’s Company.
