I don’t know if it’s true, but I read a long, long time ago that if you hold a lit cigarette lighter under a gator’s jaw in the fleshy part, he will open his mouth and let go.
This was back in the days of ZIPPO lighters, not the BIC styles.
Like I said, don’t know if true, I hope I never need to find out..................
That might be in the same vein as putting salt on a bird’s tail.
