The episode with the stolen Armored Personnel Carrier as the Dukes are being chased by the police. To ward them off, Daisy takes control of the vehicle's main gun and, with barely any instructions from her army vet cousins, shoots it at the police with pinpoint accuracy while the APC is in motion. Daisy definitely deserved that medal for "Sharpshooter of the Week" that Uncle Jesse gave afterward.
In another episode, Daisy, in the talent competition for a local beauty pageant, has to assemble a carburetor. Since Boss Hogg had taken a bribe from another competitor's boyfriend to fix the pageant, he had the lights in Daisy's booth disabled. She still finished first.
