Eccentric “30 Rock” star Tracy Morgan’s New Jersey home is filled with snakes, sharks, a sparkly Michael Jackson glove under glass and a custom-made last-supper mural featuring comics Lucille Ball, George Carlin, Bernie Mac, Richard Pryor, Charlie Chaplin, Lenny Bruce, Sam Kinison and Jackie Gleason as apostles. “That is a black African python,” Morgan explained about one snake during a tour of his home in a new Rolling Stone cover story on “30 Rock.” “She’s really nasty. Two years ago, one of those ate an 11-year-old boy in Africa.” Unpredictable Morgan also openly weeps on the NBC series’ set over its finale, pointing at a crew member and exclaiming tearfully, “I spent more time with this dude than my own family! Good times, bad times, ugly times. Awards fun, looking forward to spring. It’ll never happen again. I can’t explain.” The piece also interviews series creator Tina Fey, Lorne Michaels and Alec Baldwin, who takes a dig at his brother Stephen’s recent arrest for tax evasion. “I’m a very fastidious record-keeper of these kinds of things, so I don’t end up like my brother,” says Alec as he leaves a restaurant and “carefully files” a receipt in an “extraordinarily” fat wallet. Fey recalls the show’s ups and downs, including having to fire her “SNL” pal Rachel Dratch after specifically writing the role of Jenna Maroney for her. Jane Krakowski took Dratch’s place on the show.
