After losing his job, Ted forms his own architecture firm which he sets up in the apartment he shares with Robin. He gets off to a slow start, wasting all of his time picking stationary and pens for his new business, as opposed to getting on the phone with potential clients. Things really get off track when Robin starts sleeping with the intern Ted hired to help out around "the office," pitting Ted and Robin in a battle to keep his attention. Meanwhile, Marshall tries to make himself indispensable at work by taking on the undesirable position of the office fantasy baseball commissioner, and feeling jealous about her new boyfriend, Barney confesses his feelings for Robin to Marshall. Marshall is then able to solve everyone's problems by hiring Ted's intern to take on his task as commissioner, thereby removing him from Ted, Robin and Barney’s lives.
