Once again, a crazed Alec Baldwin has America talking. But this time it’s not about child abuse.During Thursday’s “30 Rock,” Baldwin’s character Jack stages a therapy session with Tracy (Tracy Morgan). In acting out the travails of Tracy’s family, Jack stereotypes African-Americans (mutterings about “damn collard greens”), Latinos (“Ay papi!”) and WASPs (“Now see here…”).

His rant also squeezes in some random pop-culture references. While pretending to be Tracy’s droopy-lipped, Campbell’s Soup factory-working father from North Philly, Jack delivers a spot-on impression of Redd Foxx from “Sanford and Son.” Then, pretending to be Tracy, he ends a plea for love with “Dy-no-mite!” – Jimmie J.J. Walker’s “Good Times” catchphrase.

When the therapist objects to Jack’s role-playing, he interrupts with a line about being paid a nickel to “bust up a chiffarobe.” That’s from Harper Lee’s “To Kill A Mockingbird,” when Mayella Ewell testifies, “I said, ‘Come here, n—–, and bust up this chiffa-robe for me. I gotta nickel for you.'”

Keep up performances like this, Alec, and we just might forget the choice words you left on your daughter’s voicemail.
