That whole segment about "comedians who try hard to be who they're not before they do comedy" reminded me so much of Paul Lynde. I watched the Paul Lynde Halloween Special last Halloween, and decided to check out the bonus features.
On there, there's a really awkward interview with Peter Marshall where Marshall smiles and laughs his way though reminiscing about all the times Lynde had non-stop fits of anger, drinking problems, and was really bitter about how things ended up after his earlier career in musicals. Lynde was also, acc. to Marshall, extremely jealous of other younger celebrities to boot. Marshall even laughed about how Lynde called him "Beaver Face" all the time. Essentially, Marshall tried to paint a rosy picture of Paul Lynde, and ended up doing the exact opposite. Lynde sounded like an aggressively mean man who happened to have a talent for catty one-liners. Then again, if one was in the Center Square for over a decade, that could drive anyone a bit crazy.
Apologies for the tangent, as I'm sure Paul Lynde was the last person either Tom or Marc were alluding to in that moment in the interview.
