Mike Munger links to a corruption index quiz. I was a buffalo, scoring in the bottom 4% of all quiz-takers.
In fairness, the quiz was designed for Indians to take; corruption and bribery are a good bit lower in the US, so although there were a couple of situations that would have my spidey senses tingling, it would be hard for me to say that I would even think of most of those cases as bribery.

I too am a Buffalo; my score was in the bottom 16.8%, so it would seem I am more honest than you. Hah!
