Alec Baldwin Impersonates Tracy Morgan — and Michael Jackson (Video)

"He's a man-child," Baldwin says of his "30 Rock" co-star

Alec Baldwin served up a double helping of impersonations during his appearance on Monday night’s “Conan,” singing some old school Jackson 5 to set up his impression of “30 Rock” co-star Tracy Morgan.

Baldwin, who returns for the sixth season of “30 Rock” on Jan. 12, said Morgan used to unwind in his dressing room by watching tapes of a young Michael Jackson.
