Continuity mistake: In the scene where Wakko constructs a barricade of doors in the secretary's office just to keep Yakko and Dot from busting in to answer the phone, Yakko decides to paint a door of his own, on the adjacent wall.

Continuity mistake: As Mr. Plotz tells the Warners to get out of his life, Yakko's left hand keeps changing its position on Wakko's shoulder with each shot, right before the office phone rings.
Continuity mistake: When Mr. Plotz's secretary sneezes and sends her desk flying across the office floor, the telephone on top gets knocked from its hook and dangles over the edge.
