The Case of the Stuttering Pig is a 1937 Warner Bros. Looney Tunes animated cartoon directed by Frank Tashlin.

[2] The title is a parody of The Case of the Stuttering Bishop, a Perry Mason mystery that Warner Bros. had filmed earlier that year.

In the film, Porky, Petunia, and their siblings are the intended heirs of their recently deceased uncle.

However, their seemingly benevolent lawyer, Goodwill, transforms into a monstrous killer after drinking a Jekyll and Hyde potion.

When Porky and his siblings asks who helped save their lives, the voice reveals himself as the attendee in the third row and calls the monster a big sourpuss for what he done.
