Season 2: Episode 21: House Party
Screech has the house to himself, but Screech isn't the type to throw a party while his parents vacation in Graceland. Luckily for Screech, Zack is that type of person. Zack and Slater decide to have a party there in spite of the "no parties" and "no girls" rules that Mrs. Powers left, and her prized Elvis statue gets broken. The gang has to find a way to replace the statue before she gets home.
