It's quite remarkable sometimes how... adult-oriented (and not necessarily in a dirty way) some of the things I grew up with were - just things that would go over children's heads. I remember being barred from watching the Earthworm Jim cartoon after my mum saw an episode of it - evidently she understood a lot more of it than I did!

And as you've already seen from these things that I post, they weren't gentle with their contestants in their live action programmes, either, with every one of them giving them a very reasonable chance of being killed.
