S05E12: Misty Mountain Hop

Jackie recruits the Formans to help clean out her family's mountain cabin, but decides it best not to ask for Hyde's assistance, instead telling him she is attending a doll expo. With Jackie going away, Hyde seizes the opportunity to use Jackie's cabin and invites Kelso and Fez. Donna and Eric get lost on the way to the cabin and spend the trip fighting. Hyde's plan goes wrong when Kelso gets his hand, holding his stash, stuck in a vase just as Jackie and the Formans arrive.
