Japanese TV blows ours awayFirst check out this show with these awesome contraptions:

Then for something more low brow we have this:

And in the same vein as the first one, insane dominoes using household junk:

From the same show, more insane dominoes/contraptions, take your pick of any of these:

One of my favorite parts is in one of them, the one where they make the contraption out of various movie memoribilia at this guy's house, they play the Back to the future theme using a ball rolling down stairs hitting stuff. I haven't viewed all of them but so far every one I have viewed has been great, although some are 2 parters showing a lot of the preparation.
And for something a little more, uh, out there, from the same show, is Hard Gay. Personally I think it's hilarious but your mileage may vary:

Finally there's this show that's kind of like a wacky Japanese Fear Factor ... in a library. So they have to be quiet:
