One of the crazier PR stunts I've seen for a while: Cambrian House, an open-source software company, turn up at Google unannounced and feed them 1000 complimentary pizzas .

I love this idea, but if I were a law firm serving any medium to large business, I’d take it in a different direction:  I’d surprise my biggest/best clients with enough free pizza to feed all their employees. 

If I wanted to create even more buzz, I’d buy pizza for all my business clients’ employees ON THE SAME DAY.  You could surely work a pretty good deal with the local pizza places, and think about how much everyone would talk about you. 

If I had a few thousand dollars I was thinking about spending on that secondary yellow pages book in my town, I spend my money doing this instead.  I’m sure I’d get a much better bang for my buck.
