In a voiceover for his new memoir "I Am the New Black," the "30 Rock" funnyman known for rattling off one-liners and non-sequiters went off-script and blasted former colleaguesCheri Oteri and Chris Kattan - saying the pair treated him like he was the "invisible man."
"They never going to host 'Saturday Night Live.' And I don't mean -- that's not even me, but that's what happened to me over there. They never treated me well. There were people that treated me beautifully, like Will Ferrell and Colin Quinn and Molly Shannon -- I love them. But Cheri Oteri and Chris Kattan -- I never cared for them either. F--- 'em."
"I could remember those two, especially those two people, treating me like the invisible guy. Now look where they at. Cheri Oteri, she can't even get arrested," he said.
The book hits the shelves Oct. 20.
In an interview for GQ's November 2009 issue, the comic said Lorne Michaels was among those at "SNL" who helped bolster his career.
"Lorne helped build my confidence up, being in front of an all-white audience and all that," he told the magazine. "And he told me when he hired for for 'Saturday Night Live': You're not here because you're black; you're here because you're funny."
Meanwhile, Morgan is a recent convert to the twitterverse, signing up for the social networking site for the first time last week after fans signed an online petition demanding 24-hour, unadulterated access to the comic.
"Welcome to Tracy Morgans [sic] World," he posted on his Twitter page on Oct. 8.
