Lisa Kudrow, 154
Lisa Kudrow may have played the lovable airhead Phoebe Buffay on the popular sitcom Friends, but she’s nothing like her character. With an estimated IQ of 154, Kudrow earned a degree in biology from Vassar College, where she wanted to follow in her father’s footsteps and pursue headache research. She worked for her father’s staff for eight years before pursuing an acting career. We are definitely happy about her career change.
