In this episode, the characters flash back to 10 years earlier when they first started dating. In previous flashbacks to their pre-marriage years, Doug sports a mustache. In this episode, he is clean shaven.
When Carrie drops Doug off at his fake IPS job, she pulls up on the main street. In the next shot she seems to have pulled up in an alley.
When Doug and Deacon are talking by the IPS lockers, one of the lockers' labels says 'Danny Heffernan'. This is supposed to take place long before Danny, or even Doug, began working at IPS.
When Doug pretends to go to work, he picks up his flannel shirt. It then cuts to a shot of Carrie that lasts about two seconds, then back to Doug and his shirt is already completely on.
When Doug attempts to drive the fork lift, he turns it to his right to pick up some boxes. In the next shot, the lift is turned to his left, toward the loading doors.
When Doug turns the key on the fork truck to start it, you can hear an engine start. That fork truck is electric.
When Doug is driving to look for a job, the cars seen around him are not those of the 1994-1995 period in which he is dating Carrie.
