Star Truck - S3-E31
Continuity mistake: After the Enterprise smashes Korn's ship with a mallet, we see Yakko at rest in Captain Kork's chair. A moment before he stands up, Yakko's left elbow places itself on the armrest between frames. And, between the following pair of shots, Dot jumps several feet behind Wakko when Yakko says, "Promise not to sue us."
Continuity mistake: When Ms. Flundergust is introduced to the Warners, she mispronounces Dot's name. Dot has both hands behind her back, but they jump in front of her between shots. Then within the next change of shots, both of Yakko's hands jump behind his back.

Nothing but the Tooth - S1-E76
