Continuity mistake: When Stan climbs out of the window to send himself a telegram, the window blinds are fully up inside the house, but when we cut to him going outside, the blinds are now a third of the way down.
Factual error: Oliver Hardy, inside a telephone booth, looks up Stan Laurel's number in a large directory. He finds the number on a page which is about one-fifth of the way from the beginning of the book. After he calls Stan and Stan hangs up on him, Ollie looks up the number again. This time he finds the number on a page which is about three-fourths of the way from the beginning of the book. Names beginning with "L" would not be on either of those pages but would be approximately two-fifths of the way into the book.
