Porky's Pet is a 1936 Warner Bros. Looney Tunes cartoon directed by Jack King.
When Porky reads the telegram, he sees it is an offer from a big shot producer in Broadway, New York City, who wants Porky and his pet ostrich, Lulu, in his show, offering $75 a day (equal to $1,647 today).
Porky wants the job, so he tells Lulu the good news and takes her on a leash to the train station.
Porky and Lulu get on board, but the conductor kicks them off, on account of a "no pets" policy.
Porky sees him, shoves the noisy accordion down Lulu's throat to her stomach, stuffs her inside a guitar case and trims her sticking out tail feathers.
