Quote from Kelso in The Battle of Evermore
Fez: How are we gonna break into Leo's apartment? Kelso: [bounces against the door] We need a credit card to slip in the door. Ponch used one on CHiPs once and the lady he rescued was so grateful they did it. Hyde: Kelso, if we had a credit card, we could buy a sledgehammer and break down the door. Jackie: If we had a credit card, I'd be butt-deep in Jordache right now. [Fez turns the handle and opens the door]
