A good idea, if i may say so:
Al Franken suggests we all yell when Bush accepts the nomination. It's sort of like the worldwide antiwar protests, but with less walking! Perfect for lazy people! And its a great way of expressing frustration at Bush, it would likely get the protests even higher visibility if it had a nice centralized action like this. Someone organize this in NY!
The official site is here.
But, like i just posted on my blog, I always scream at Bush when he's on my tv anyway. So i'd feel very included if this was some sort of symbol of national frustration.
