Other than 'Eegah!', I actually remember him best for the insane amounts of guest spots he used to do on nearly all of my favorite TV shows: 'The Wild Wild West', 'The Twilight Zone', 'Kolchak', 'Gilligan's Island', etc., etc..
Last night I watched the episode of 'The Monkees' where he played a Frankenstein's monster type character for whom the band were hired to teach how to become a rock star. The '60s were a weird time.
