Which Looney Tunes duck is known for his lisp?

Daffy Duck is the Looney Tunes duck known for his distinctive lisp. The speech pattern became one of his defining traits, especially in later cartoons, where his exaggerated pronunciation heightens his boastful, frantic personality.

Daffy first appeared in the 1937 short “Porky’s Duck Hunt,” created by animator Tex Avery and developed with Bob Clampett. He began as a highly energetic “screwball” character before later directors, including Chuck Jones, gave him more jealousy, ambition, and rivalry with Bugs Bunny.

The origin of Daffy’s lisp is disputed. One popular explanation connects it to producer Leon Schlesinger, while voice actor Mel Blanc attributed it to the character’s extended lower jaw making “s” sounds difficult. Porky Pig is associated with a stutter, and Elmer Fudd with mispronunciation, but Daffy’s lisp identifies him.
