Season 2: Episode 26: The Juicer
Cliff buys an expensive new juicer and forbids Rudy from going near it. Clair asks Vanessa to keep an eye on Rudy and Peter for a few minutes while Cliff is at the office. Vanessa gets distracted by a phone call from a friend, and a bored Rudy and Peter decide to go to the kitchen for a snack. They cannot find any jelly, so Rudy decides to put some grapes in the juicer. The juice goes flying all over the kitchen, and Peter runs home and hides in the clothes hamper. Cliff and Clair assign Vanessa and Rudy to clean up the mess. However, Clair points out that Cliff probably should not have left the juicer plugged in.
