Season 5, Episode 9 The Lousy Week

First Aired: October 2, 2000

The kids at Lakewood Elementary School have their own itchy and scratchy show---courtesy of head lice. The trouble begins with Muffy, but when the school nurse tells her what's wrong, she won't believe it. "I couldn't have head lice," she declares. "That's something dirty people get." Not necessarily. The good news: it's easily treatable.
