Seriously it makes you go to sleep. I would quote some of the site, but it wont let me copy any of the text for some reason. Check it out though, it'll make you laugh. And watch the video on the main page lol.
If you want to relax, I've found the best relaxer on the market. Just drink anything alcoholic followed by eating anything sweet. You'll fall asleep faster than a narcoleptic in church.
