From an unknown year: William M. Gaines, publisher of Mad Magazine, appears on To Tell the Truth. My thanks to Kliph Nesteroff for telling me about this.
My only guess as to the year is that at the end, mention is made of Dick DeBartolo, who worked on To Tell the Truth and also wrote for Mad. Gaines says that Dick has been in the magazine for seven years without missing an issue. DeBartolo first appeared in Mad in issue #103, which was dated June, 1966…so if Bill's being accurate, this episode would have been around 1973. (DeBartolo has kept that streak going, by the way. He has now been in Mad every issue since then for a total of 399 consecutive issues over 42 years.)
Dick, by the way, sent me a note I ran here some time ago about this segment on To Tell the Truth. Here it is.
And here's the clip. You may notice that the audio is a little out of sync. So was Bill Gaines.
