The laughs keep coming in Season 3 of this classic spy spoof series from co-creators Mel Brooks and Buck Henry. A slew of guest stars, including Carol Burnett, Milton Berle, Don Rickles, Regis Philbin, Bob Hope, Joey Bishop, Buddy Hackett and Johnny Carson add to the fun, as inept secret agent Maxwell Smart bumbles his way through 26 episodes, including the Emmy(R)-winning “Maxwell Smart, Private Eye,” and the hippie send-up “The Groovy Guru,” voted one of the 100 best episodes of all time by TV Guide.
