Heard the second one a couple a weeks ago when I had my burm at the tractor festival except the snake had been refusing prey for a couple weeks in preparation for eating the woman.
I tell people that its false and the obvious flaws in the stories but this one has a simple solution the snake should be sleeping in its secure cage regardless of size, besides the fact a snake isn't going to refuse something properly sized foodwise to eat an excessively large prey item. Also someone is way overestimating the brainpower of snakes, they just can't plan things that far ahead of time,while better than a goldfish I don't think anything more than 20seconds ago enters their minds.
