LISA FINDS A SURPRISING BRANCH OF HER FAMILY TREE ON AN ALL-NEW "THE SIMPSONS" SUNDAY, FEBRUARY 21, ON FOX

Wren T. Brown ("Curb Your Enthusiasm") Guest-Voices

When Miss Hoover asks her students to research their family history, Lisa is horrified to discover that most of her ancestors were bad people � a motley crew of horse thieves and deadbeats. But while rummaging through the attic, Lisa happens upon a diary kept by her ancestor, Eliza Simpson. As Eliza's story unfolds, Lisa learns that her family was part of the Underground Railroad, a group that helped slaves escape to freedom. Eliza recounts liberating a slave named Virgil (guest voice Brown), but when Lisa presents her findings at school, some of her classmates refute it, leaving Lisa determined to exonerate her family's name in the all-new "The Color Yellow" episode of THE SIMPSONS airing Sunday, Feb. 21 (8:00-8:30 PM ET/PT) on FOX.
