The snake

The snake in the "Diary of Adam and Eve" sequence at first appears to have a cigarette in his mouth, but then in a closeup it sure looks like a match. I don't know why the snake should have a match in his mouth, but perhaps someone complained about the cigarette (if it was a cigarette) during the production phase. Personally, I'd have kept it a cigarette, as that adds to the snake's creepiness. Any ideas why they have a match in the snake's mouth?
