As Harris fills out a robbery report for a Hasidic Jew who was a target of a diamond theft, Barney starts to feel his are when Wojo brings in an aging Olympic hopeful who causes a scene practicing the javelin in Central Park and he makes a comment about his age and physique.

When the detectives hold an open house for the twelfth precinct, the only guests they have are a handful of vagrants. Wojo and Harris work on tracking down a serial arsonist at the nearby piers. When Barney announces to the guys that he's moving back home, he's in for a surprise when the hotel informs him he won't be getting his deposit back.
