Tracy Morgan has some choice words for his former Saturday Night Live co-stars, Cheri Oteri and Chris Kattan.

According to Defamer, the 30 Rock star says his ex-colleagues mistreated him during their SNL years together in his upcoming autobiography, I Am the New Black — and judging by his ad-libs during his audiobook recording, Morgan’s not over it.

“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 says in the clip. “Where’s Chris Kattan now? They never going to host Saturday Night Live.”

The Emmy-nominated Morgan, who has hosted SNL, adds that Will Ferrell, Colin Quinn and Molly Shannon treated him “beautifully.”
