Okay, call it a hazy memory... maybe it wasn't the "powers that be", but perhaps Wallace himself felt the show might ruin his credibility. Until I saw him host the TTTT pilot, I couldn't picture Mike Wallace hosting a game show. On 60 Minutes, Mike was certainly not someone that could make a nervous person feel at ease. On the contrary, those he interviewed could be quite intimidated by him. He interviewed Johnny Carson on 60 Minutes in 1979. It's no secret that Carson HATES being interviewed, and when originally agreeing to be interviewed on 60 Minutes in 1976, he got cold feet and stopped the proceedings. However, he agreed to try again. Mike steered clear of asking questions about his previous marriages (he was still married to wife #3 at the time) and his childhood but briefly brought up Johnny's intolerance of alcohol. Johnny said he doesn't handle alcohol well, which is why he rarely drinks. On The Tonight Show, he was making fun of some celebrity until he found out the celeb was an alcoholic, and the jokes stopped. Wallace, in response to that, quipped "It takes one to know one", and Carson replied with a sneer "oh you're cruel."
