Losing Weight, Giving Food: Body Tech Gym in Brazil developed a program where every pound you shed, a pound of food gets donated to needy children.

Craving something from abroad?: We’ve seen swap programs before – but mmMule is looking to tap travelers. Let’s say I want Tim Tams (from Australia) – I would post my wish on the site and a traveler who is coming from Australia to New York will pick it up for me.

Yawn Bomb: To promote BEING FUN, Carnival Cruises creates a site for people to share links that they think are boring. Type the “boring link” on this site and it will generate a “yawn bomb” – the contents of the “boring link” with someone yawning over it.  It then gives you a new URL so you can “yawn bomb” your friends.
