 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 (Billy Gilbert), 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.
