Peter goes to the therapist with his girlfriend to try to fix his relationship and they start talking about his work.
Peter: So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life.
Dr. Swanson: What about today? Is today the worst day of your life?
Peter Gibbons: Yeah.
Dr. Swanson: Wow, that's messed up.
