Lucky needs money to throw Luanne the extravagant wedding of her dreams. When he's injured in a fall from Dale's basement steps, a corrupt lawyer encourages Lucky to get litigious towards anybody with money who could possibly be blamed.
In order to pay for the big expensive wedding of her dreams, Luanne's husband-to-be Lucky sues Dale in hopes of getting a big cash settlement, like what he's received in past lawsuits, when he accidentally injures himself shortly after going to work for Dale's extermination service "Dale's Dead Bug".—skin-and-bones
