It's where they cut back to the tuft of hair, skin and blood after the kid's beaned himself and is about to drown in a puddle.
And the bit where the kid's drowning in slurry.
I remember one where a kid died after playing in a grain silo and had several dozen tons of grain dumped on him. It wasn't a big problem growing up in Croydon, of course, but it still got the message across.
