When it comes to bribes, free pizza is as effective as bags of money in Denver. 

Foxnews.com reports the Denver Police Department, on July 29, launched a new initiative to reward courteous or law-abiding citizens with pizza. The initiative is sponsored by Alpine Bank and Papa John’s, and it's codenamed “You Got Caught Doing Something Right.” The campaign follows up on previous successful pizza payoffs for good behavior pioneered by two Midwestern jails. Residents can earn pizza cards, valid for a free Papa John's pie, by using trash cans instead of littering, not jaywalking, helping others across busy intersections and other positive behaviors.
