Other mistake: After the turkeys start attacking in "The Running of the Turkeys", Mr. Fishoder and his brother start running. In that clip a Turkey pops out the side of a guy's head. Look in the mid lower right side. Looks like a design error. Pretty big error, no slow down needed to see it. (00:05:20)
Burger Wars - S1-E10
Continuity mistake: As Mr. Fischoeder talks, the plate of Meatsiah burgers in front of him disappears and reappears between shots.
Sacred Cow - S1-E3
Continuity mistake: When Animal Control Guy walks over to Moolissa and states the cow must have had a heart attack, his shirt buttons, badge, shoulder mic, etc, are at his left. Then Animal Control Guy begins to walk back to his van, and watch as mid-shot his shirt buttons and everything else switch to the opposite side (if it's paused we also see his mic cord clips through his arm). (00:17:55)
Mutiny on the Windbreaker - S3-E4
Other mistake: When Gene slaps the pennies out of the woman's hand with the glasses her eyes turn white with an animation error where her coat and mouth intersect. (00:16:45)
