The Dick Cavett Show with guest Shirley Maclaine (1971)

Password Plus with celebrity contestant David Letterman (1978)

The Phil Donahue Show with guest Phil Hartman (1987)

Phil Hartman does a brilliant impression of Donahue right in front of the man... and the square audience laughs in all the wrong places.

The Tonight Show with Johnny Carson 10th Anniversary Special with guests Jack Benny, Joey Bishop, George Burns, Jerry Lewis and Don Rickles (1973)

The Phil Donahue Show with guest Jerry Rubin (1970)

Donahue was rather wise to question the sincerity of Yippie Jery Rubin in this interview. Just six years later, Rubin cleaned himself up and joined Wall Street rejecting his former life as a Yippie. Ironically, Donahue would come to emulate the anti-war politics that Rubin was somewhat of a poster child for in the late sixties. "Let's not be afraid of ideas," says Donahue near the end of this episode. Phil was extremely perceptive. Rubin occasionally makes some valid points, unfortunately, as Donahue noted, they were rather short on sincerity - and high on obnoxiousness. Read Rubin's yuppie treatise Growing Up at 37 (1976, Warner Books) for more on his transformation into a Ronald Reagan Republican.

And the Winner Is...

Thanks to all the people who entered our Johnny Carson contest sponsored by Respond2 Entertainment. We received over one hundred responses and even in this age of Google, two of you still got the wrong answers. Perhaps you were taking the noble route of using your own knowledge rather than the easier way. Good on you - but you still lost. The answers are:

1) Who Do You Trust (note the lack of a question mark, however, no points were subtracted from those entries that included one).

2) Johnny was replaced by my old friend (emphasis on old) Woody Woodbury.

3) The announcers on the two incarnations of the program were Ed McMahon and Bill "Friday Night Fights" Nimmo.

A big congrats to Classic Television Showbiz reader Jason from Montreal, Quebec, who was the fourteenth person to answer all questions correctly.
