When the Warner Bros. animation studio briefly outsourced cartoon production to DePatie-Freleng Enterprises (DFE) in the 1960s, Daffy Duck became an antagonist in several cartoons opposite Speedy Gonzales, who refers to Daffy as "the loco duck." In "Well Worn Daffy" (1965), Daffy is determined to keep the mice away from a desperately needed well seemingly for no other motive than pure maliciousness. Furthermore, when he draws all the water he wants, Daffy then attempts to destroy the well in spite of the vicious pointlessness of the act, forcing Speedy to stop him.
