If I Had a Hammer is the 11th episode of Season 7 on FOX drama soap Beverly Hills, 90210.


On Thanksgiving Brandon and the gang help Willie, one of Nat's Peach Pit employees, build a house through the organization Habitat For Humanity. During the holiday, Brandon declares his friendship with Steve over when he discovers that Steve plagiarized his term paper. After returning from Las Vegas, David goes to a therapy center and is shocked when he hears his diagnosis, and a romantic weekend for Kelly and Mark backfires.


During an argument with Donna in the student union, David throws a tantrum and cuts his hand on a glass. He must see a psychiatrist after displaying hostile behavior toward the ER staff. Mel agrees with the doctor's recommendation that David be held 72 hours for observation. David is diagnosed with a mild form of manic depression. His mother comes to see him and advises him to moderate his behavior; he will not require medication if he seeks therapy and stops drinking. David thanks Donna for her support and they decide to get back together. Steve faces plagiarism charges; Professor Randall, who assumed control of the independent study course after returning to CU, recognized Brandon's writing.

Randall still holds a vendetta against Brandon and brings collusion charges against him. Kelly's and Mark's plans for a romantic weekend getaway are foiled by a lost reservation. They finally secure a motel room, only to come down with food poisoning. The gang helps Willie build a house that his family will receive from Habitat for Humanity. Val displays construction skills as a result of working with her contractor father, but hints to Clare that she has few happy memories of her dad. Everyone eats Thanksgiving dinner inside the unfinished house.
