McDonald's restaurants in Japan were offering Big Macs for half off their normal price if people demonstrated a commitment to preventing climate change. To "demonstrate" this commitment, people were asked to download a form from the environment ministry's web site. Enough people visited the site to bring it down for the first time ever. Let me think this through... the more Big Macs eaten, the more cows killed, and the less flatulence that contributes to global warming. I guess it does make sense.
