The loan application for Walt Comeau that Janine Roby sees that reveals his birthday also lists his Social Security Number (SSN). Prior to 2011, the first three digits of a SSN were based on the state where the application was processed. Based on the leading "344" of the SSN shown, Walt Comeau must have been a resident of Illinois when he applied for a SSN. This is either intended as an extremely subtle way to establish that the character is from Illinois or a geographic error based on not realizing that SSNs were geographically encoded in this way. However, Dennis Farina, who plays Walt Comeau, is from Chicago, Illinois, so this SSN would at least be consistent for the actor, although not necessarily for the character.
