morganmemoir.gif30 Rock star Tracy Morgan cut loose while reading on the audiobook version of his memoir, actually improvising about his post-Saturday Night Live relationships.

Gawker captured a snippet from the upcoming audiobook, as Morgan has some angry memories about fellow SNL castmembers Chris Kattan and Cheri Oteri and then cuts loose with some other thoughts. Morgan co-wrote the book with Anthony Bozza for Random House’s Spiegel & Grau imprint.

Here’s more from the Gawker post: “But the grudge apparently runs even deeper, because when Morgan sat down to record the audio version (in the clip above) of that passage, he started ad-libbing, expanding on his earlier points: Morgan says he still counts Will Ferrell, Molly Shannon and Colin Quinn as friends, but as for Oteri and Kattan: ‘F*** ‘em.’” (Via The Millions)
