Mr. Mouse Takes a Trip (1940)
Pete: You know, I used to have a little cat once. And when it was left all alone, it'd cry... MEEEEEEEEEOOOOOOOOWWWWWWW!
Pete: [bumps into Mickey, dressed as an Indian] Oh, I beg your pardon, Chief.
Mickey Mouse: [Indian's voice] How.
Pete: [to Mickey, who is wearing Pete's conductor's coat] He-he-hey you! Did you see a mutt and a little runt around here?
Mickey Mouse: [Gulp] Yeah, they went... Ahem!
Mickey Mouse: [Deep voice] ... they went that way.
Pete: Thanks, conductor.
Pete: Conductor? W-Why, that's me!
Pete: Train leaving for Albuquerque, Amarillo, Azuza...
[babbles at a very fast pace]
Pete: ... and all points west!
Mickey Mouse: Hurry up, Pluto!
[He and Pluto ran inside the train in a hurry]
Pete: Hey, you! No dogs allowed!
[He kicks out Mickey and Pluto and throws back their luggage]
Pete: So, it's you, huh?
Mickey Mouse: [nervously] Yeah. It's me, I guess.
Pete: All alone, without your dog.
Mickey Mouse: Yeah, all alone.
Pete: Hey, you! This baggage belongs up there!
[He throws Mickey's bag which has Pluto in it up in a luggage rack]
[Pete had just succeeded in getting Mickey and Pluto off his train. They end up on the train tracks]
Mickey Mouse: Gosh, Pluto, I wonder how far it is to Pomo...
[he then looks up and sees that they've wound up near a train station for Pomona]
Mickey Mouse: Pomona! Hey, we're here!
[Mickey and Pluto shake hands]
