30th in Mickey's cartoon series is the simple yet charming Mickey Steps Out. The short is a standard song-and-dance but does include an interesting piece of dialogue spoken by a certain pup.
The short opens with Mickey getting ready for a day out. The Mouse's routine includes shaving, a funny little gag in itself.
On the way over to Minnie's, Mickey is knocked over by the ever playful Pluto. By this time, it has been firmly established that the pup belongs to Mickey.
Minnie of course is playing her piano, and Mickey can't resist the urge to dance and perform tricks for his sweetie.
Unfortunately Pluto happens to spy a black cat, and soon the chase is on inside Minnie's humble abode. After wrecking the piano, the two animals take the Mice on a wild rug ride around the house.
The chase ends with the cat tricking Pluto into running headfirst into the stove, which causes soot to fly everywhere. Covered in soot from head to toe, Pluto bursts from the stove and shouts "Mammy!" a reference to Al Jolson. This marks Pluto's second time talking, the first having been in The Moose Hunt.
