Synopsis by Josh Ralske
The Griffins attend a school basketball game to see Chris (voice of Seth Green) come off the bench...to clean up some sweat. "You really wiped the floor with that towel," Peter (voice of Seth MacFarlane) tells him later. Stewie (MacFarlane) is fascinated watching the cheerleaders pump up the crowd. "I must discover the secret of their mind control powers," he vows. Peter is perturbed when Chris begins talking "street" in the car on the way home. Cleveland (voice of Mike Henry) suggests that "maybe Chris has adopted another culture's mannerisms because he doesn't know enough about his own." So Peter takes Chris to the Museum of Irish Heritage, where they learn that Ireland was a futuristic advanced civilization before the invention of whiskey. But looking at his family's genealogy in the Quahog library, Peter is shocked to discover that one of his ancestors, Nate Griffin, was black and a slave. Peter is determined to honor his heritage, so he sets about trying to learn "how to be black." He embarrasses himself at the Apollo, and in an African-American Studies course. Things take a stranger turn when Peter learns that Lois' (voice of Alex Borstein) ancestors actually owned Nate Griffin. He demands and gets reparations from Lois' father, but his new friends at the Quahog African-American League and Lois are outraged when Peter spends the money turning the living room into his very own Pee-Wee's Playhouse. Stewie, meanwhile, ingratiates himself to the cheerleading squad, determined to learn all their secrets, including the reason for "their obsession with the homosexuals from *NSYNC."
