What is the full name of the person who screams to get the piano out of the way?
In a music store, a woman orders a player piano as a surprise birthday gift for her husband. She tells the manager her address — 1127 Walnut Avenue — and he hires the Laurel and Hardy Transfer Company to deliver the piano in their freight wagon.
The duo soon learn from a postman that the home is at the top of a very long stairway. Their attempts to carry the piano up the stairs result in it rolling and crashing into the street below several times, twice with Ollie in tow. During their first attempt, they encounter a lady with a baby carriage trying to go down the steps; in trying to let her pass, they knock the piano back down the stairs. After the lady laughs at them, Stan kicks her in her backside, causing her to punch him back and hit Ollie over the head with a milk bottle. Stan and Ollie then heft the piano back up the stairs. The angry lady tells a policeman on the corner, who kicks Ollie twice and hits Stan with his truncheon after the latter suggests the officer is "bounding over his steps" (i.e. "overstepping his bounds"). Meanwhile, the piano has rolled down the steps again.
The two doggedly persist in carrying the piano up the stairs for a third time. Halfway up, they encounter the short-tempered and pompous Professor Theodore von Schwartzenhoffen, M.D., A.D., D.D.S., F.L.D., F-F-F-and-F. He impatiently tells them to take the piano out of his way; he should like to pass. Ollie very reasonably and sensibly suggests he walk around, which sets off the Professor in a fit of Teutonic rage. He screams at Stan and Ollie to get the piano out of his way, and Stan knocks the Professor's top hat down the stairs and into the street, where it is crushed by a passing vehicle. The outraged professor leaves, loudly threatening to have the two arrested.
