Newman claimed that he once worked the same postal route as American serial killer David Berkowitz, otherwise known as the "Son of Sam", who was working for the Postal Service at the time of his 1977 capture; Newman claims "we once double-dated". When asked what Berkowitz's postal route was like, Newman commented the route had "a lot of dogs", but joked that they only told him "to lay off the snacks" (a reference to Berkowitz's claim that talking dogs possessed him to go on a killing spree). Newman retains Berkowitz's mailbag as a valuable collector's item. When the police come to arrest him in "The Engagement", his first words to them are, "What took you so long?", the same words Berkowitz used when arrested. In real life, however, Berkowitz did not have a mail route while employed at the Postal Service. At the time of his capture he worked as a letter-sorter.
