This Thursday’s return of 30 Rock isn’t the only thing Tracy Morgan fans should be looking forward to. Next week’s release of the comedian’s new book, I Am the New Black, promises to give us more backstage group than the fictional NBC program could provide.

In the autobiography, Morgan talks about his years on Saturday Night Live and is more than candid about those he liked and disliked. Part of what can be heard on an audio recording of the book is apparently an ad-libbed version of what is on the page. Either way, you might not think about former late-night players Cheri Oteri and Chris Kattan the same way again.

“I can remember being on Saturday Night Live and feeling like I was at the bottom of the totem pole. I can remember when people like Chris Kattan and Cheri Oteri would probably look down upon me. I can remember those two - especially those two people - treating me like I was the invisible guy. Now look where they at. Cheri Oteri - she can’t even get arrested. Where’s Chris Kattan now? They never gonna host Saturday Night Live.... They never treated me well. There were people who treated me beautifully like Will Ferrell and Colin Quinn and Molly Shannon—I loved them. But Cheri Oteri and Chris Kattan never…I never cared for them neither. F**k ‘em.”

Morgan’s book hits shelves on October 20.
