Looney Tunes Baseball Card 89

Porky shared his stutter with the voice actor who originally played him, Joe Dougherty, who actually did have a stuttering problem. Because Dougherty could not control his stutter, however, production costs became too high and his recording sessions took hours. The versatile Mel Blanc replaced Dougherty in 1937. Blanc continued the stutter; however, it was harnessed for a more precise comedic effect (such as stumbling over a simple word only to substitute a longer word without difficulty).This is parodied in A Connecticut Rabbit in King Arthur's Court, where Bugs Bunny struggles to pronounce the word "porcupine", which Porky pronounces with no trouble.
Porky's Duck Hunt was released in 1937, and Blanc officially became the permanent voice of Porky until his death in 1989. In later interviews, Blanc often made the claim that he intended Porky's stutter to be suggestive of the grunting of actual pigs (although other cartoon pigs do not have such a severe stuttering problem). Porky is currently voiced by Bob Bergen.
