Rob runs into Harrison B. Harding but Rob doesn't recall who he is. Harrison knows everything about Rob which bothers Rob greatly. So the Harrisons come to dinner, Rob thinks Harrison may be a con man. Ritchie tells Harrison where Rob's wrist watch is.Rob calls the police to report a possible robbery (it has not happened yet) So in order to find out more Rob listens with the glass up against the wall (the wrong end of it which cause Rob to get Tomato Juice in his ear.) When the police come Harrison explains he needed the watch to correct the spelling of Petrie (Harrison forgot to add the letter e.)
