Anyone up for tormenting our poor Sammy with it, or something similar? heh  Details and logistics and all that totally up to you. You can even just pretend this exists in America so you don't have to come up with a reason to get the boys to Australia. :-) I just think this sounds terribly awful but also fascinating.
