Enter Batgirl, Exit Penguin - S3-E1

Plot hole: When he abducts Alfred, believing him to be a minister, Penguin suffers a peculiar memory lapse. He's encountered Alfred twice before in previous episodes, even kidnapped him once before (knowing full well that he was Bruce Wayne's butler). Yet here, he fails to recognize Alfred at all.

The Bird's Last Jest (2) - S2-E28

Plot hole: Batman proudly tells Robin that he knows Penguin's men are out of ammo because he's been counting all the bullets. But he'd have no way to know how many rounds they had to begin with, so he couldn't possibly know that they've run out. (00:05:30)
