The Griswolds and the Manequin

Original ending where the Griswolds go to Roy Wally's house and hold their family hostage has never been released, but Chevy Chase claims he is a tape of it. Clark points a BB gun at Wally, forces him in a security guard and business associates to sing and dance Wally World theme songs. And then there's some rumor that the girl on the red Ferrari shows up and is as Wally's daughter. The last postcard you could see is them on the airplane. There's a probably not a great hijack vibe in the 80s. But much better now.
