Das Stacheltier - Ein Pferd müßte man haben (1961)

Psichinski rings Mr. Semmler's doorbell and alerts him to strange noises in the attic. Together they sneak upstairs and discover a full-grown horse, which they report to the police officer. He triggers the alarm. The fire department and several workmen marvel at the event and ponder how it could have gotten there in its full size. The return transport requires structural measures and reconstruction work. After completion, Psischinski's house resembles a "jewel box". Later, the policeman asks Psischinski how he "managed" the matter and learns that he had brought a foal there 1½ years ago in order to draw the attention of the public, especially the tradesmen, at the appropriate time so that work that was difficult to carry out could finally be completed. Shaking his head, the official, who also owns a house, leaves the property with the comment: "You should have a horse!"
