Mark Evanier is a writer of TV and comics with an interesting blog. He's also an amateur magician (and Magic Castle member) who often has something to say about magic. He's just found an online episode of Sammy Davis Jr.'s 1966 show, in which one of the guests is Don Alan. Don's bit starts at about 26:34,
, and he fools the doo doo out of Joan Rivers and Mickey Rooney with a chop cup.
(Oddly enough, Sammy doesn't appear on the show -- it was guest hosted by another amatuer magician -- Johnny Carson).
