The first is an actual game you can play on the internet called Pootris.
(Pootris = Poo + Tetris.)
It's totally gross, but kind of addictive. It's also one of those things you should forward to every guy you know, because they'll no doubt think it's the greatest thing ever.
From the Pootris website...
It's toilet time, and you're about to explode. Unfortunately, taking a dump is a little more challenging than it used to be. You'll have to get the pipes from the toilet to the sewer, or you could experience some seriously smelly overflow in this Tetris/Pipedream hybrid game."Warning: if you're at work, you might want to turn down the volume on your computer. The website plays really obnoxious music.
The second thing I found is a video of a Japanese game show called "Human Tetris."
