vanessa's fast talking friend on cosby show
List of The Cosby Show characters One of Vanessa's best friends in high school was a girl named Kara (played by Elizabeth Narvaez), who could ramble on about nothing in particular at high speed. Whenever Cliff—who once referred to Kara as "Turbo Tongue"—was on the receiving end of her babbling, he would always reply with a bewildered "Thank you." Vanessa appeared sporadically in the final two seasons of the series due to the character being away at college.
