This campaign has been online for a few weeks now, but it's worth posting anyway. Save Gerard (Sauvez Gerard) is an advertainment site launched by Discovery Channel in France.
The idea is to save Gerard and his bunny who still haven't found out about the existence of Discovery Channel.

The site features a series of funny videos and highlights the programs currently showed on the Channel. The goodies section allows people to download a logo and print it out on a t-shirt. You can also support him leaving a message in the board or send around postcards to your friends.
