For Pete's Sake is a 1974 American screwball comedy film starring Barbra Streisand and directed by Peter Yates.

His pompous sister-in-law Helen delights in reminding them that an early marriage robbed him of a college education and how much better off she and her husband Fred are.

When Pete gets an inside tip on pork belly futures, Henrietta borrows $3,000 from a Mafia loan shark to purchase the commodity.

The title tune "For Pete's Sake (Don't Let Him Down)," was written by Artie Butler and Mark Lindsay, and sung by Barbra Streisand.

In his review in The New York Times, Vincent Canby called the film "an often boisterously funny old-time farce" and added "The movie may not hold together as any kind of larger comic statement, but the laughs are self-sustaining throughout...Miss Streisand's comedy range is narrow, like a cartoon character's, but For Pete's Sake operates almost entirely within that range.
