God's honest truth, this is probably the skeeziest preservation I've ever heard of.

I think I have an idea that could 1-up that, though I will *not* be the one to implement it. It might not seem as vulgar, but I think it's more likely to influence kids...

The Film: Sonic the Hedgehog The Movie

The Scene: In the original Japanese VHS of the Sonic OVA, Sonic flips the bird at Metal Robotnik. In every release of the film made afterwards, even the so-called uncut releases (in some english releases, certain scenes are removed, like Sara imagining that she is married to Robotnik and breastfeeding one of their kids, Tails accidentally groping Sara's boob, etc. Other english releases have these scenes intact using the same english dub.) Sonic's hand has been reanimated to look like he is giving the pointer finger.

All you would need is that original japanese vhs and either a us or jp "uncut" dvd, cover Sonic's hand from one of the ladder resources with the former, and watch in horror as your kids learn an obscene gesture for the first time.

Kids might not get the boob joke, but they might flip people off...

Yes, yes there is. Behold "The Blah Story" Enjoy.
