What happened to Lisa Turtle? Lark Voorhies’ mother says she is bi-polar. Lark denies it, but clearly she is struggling. She can barely complete a sentence in this video. Yet, her date isn’t phased in the least. It’s sad. (Her outfit is even more depressing. 1993 called and wants the blazer back.) First, Jessie Spano made”Showgirls.” Then, Screech starred in a porno and now this. Bayside High School will never be the same.
