Dewey is a proud supporter of the crooked Hogg family values.
Like his little brother Hughie, Dewey grew up with the Dukes and tormented them at every opportunity. As children, Dewey tried to push Daisy off the roof of the house in a soapbox airplane. He also cheated her out of first place in the all school spelling-bee, which Daisy is still upset about.
Dewey, like Boss and Hughie, started his scams young. In the third grade, Dewey faked the bubonic plague and got the school closed for a week. In the ninth grade, Dewey sold all the school chairs and desks to get two moonshine stills. As Waylon said, "Dewey makes his Uncle Boss look respectable."
As an adult, Dewey, comes back to Hazzard, claiming to be suffering from a rare - and ultimately, fatal - illness. As his last wish, he hopes to raise $100,000 for a new children's hospital. Of course, it's all part of a scam to cheat the folks of Hazzard out of their money. But Dewey, knowing the fraud will eventually be found out, plans to have Uncle Jesse framed for the scheme, leaving Luke and Daisy to expose Dewey.
