Plot hole: Gary is still "alive" because his head/brain was not destroyed when Shiela killed him. However, over the course of the show, we see many bodies in the freezer or otherwise with the heads still intact yet none of them are still "alive" in spite of the fact that their brains have not been dispatched.
Continuity mistake: The organ Jean is holding while talking keeps changing shape without her eating it. Sometimes the edge is jagged, has a bite out of it, or is smooth. And we usually see her holding it, and she's not twisting it around.

Continuity mistake: When Joel takes the note off the door, the knife slices the paper. But in the next shot, where they're facing the camera, the note has a chunk ripped out on top.
Continuity mistake: When Sarah takes Eric's taquito, she takes with her right-hand and switches it to her left. In the next shot it's back in her right hand.
