A Sucker For the Suck-O-Matic / Canned - S1-E8
Continuity mistake: In "Sucker for the Suck-o-matic," the TV opens up Rocko and Heffer's heads to scrub a weird product on their heads to make them buy the Suck-o-matic. The TV leaves their heads open when taking their brains out to dribble. In the next shot the heads are closed while the TV dribbles the brains. Then in the next shot, their heads are back open while the TV puts them back.
