It originally aired on the Fox network in the United States on January 12, 2003. In the episode, Homer disappoints Lisa on her birthday when he gives her a thoughtless present. He realizes that he knows little about her and decides to hire private detective Dexter Colt to spy on her.

Feeling sad, Homer gets an idea from Moe to hire Dexter Colt, a private detective, to find out facts about Lisa.
