I've Got You Under My Skin/In a Jam/Junk in the Trunk - S1-E12
Continuity mistake: Junk in the Trunk: At the start, there is a shelf on the wall with no tape dispenser on it. Then, a moment later, Lumpy gets a piece of tape from a tape dispenser that suddenly appears on the shelf. In the next shot, the tape dispenser disappears. (00:14:47 - 00:15:15)
