Didn't He Hang Out With Norm McDonald a Lot?

A book a few years ago in 2019 from Susanna Kahan, unless you misspelled Callahan. It was called a great pretender and basically said, this guy's kind of a fraud. She also didn't quite but came close to accusing him of flat out making up about half the people. Didn't he hang out with Norm McDonald a lot to you? Yeah, I think there were pals.
