Walter Matthews is the father of Jessica Matthews who appears in Dumb and Dumberer: When Harry Met Lloyd and is portrayed by Bob Saget. He takes an instant disliking to Harry during their first encounter.
When meeting Harry Dunne, Walter enters the room shocked to hear Harry insulting Jessica. Unbeknownst to him, Harry is repeating what Lloyd Christmas is saying through the window (who was getting angry at a puppy that barked at him). He is later told by his daughter that Harry is special but judging by his attitude towards Harry, he is not so convinced. He is also irritated by the fact that Harry keeps referring to him as "Charlie" and that he is wearing his wife's formal suit. Later, he goes to the bathroom and goes completely ballistic when he sees Harry's melted chocolate covered all over the bathroom, which of course, he believes to be feces.
After Principal Collins is arrested for fraud and embezzlement, he bumps into Harry (who is covered in mud) with his car. Once again, he believes that he has completely covered his car in feces and demands that Harry clean it up but he and Lloyd run away before he can take action.
