They also made some other cool projects, such as “low rent in tel aviv”,”prepare from zombies attack”, check their site for more info.
Nice stuff, original+humor and to the point.
On a similar note, someone invested a lot of effort in this funny site http://www.kidsourcing.com. It offers parents for rent, when you are to busy to be with your own kids. The site survey is “Should parents sacrifice everything for their kids?” 🙂
