Behind the line
What it means
Our interpretation.
It is Biff in one sentence: a bully who sets the trap, springs it, and then lectures the victim for falling for it. The joke runs on repetition, because the scene is played almost identically thirty years apart, which tells you the McFlys have been losing to the Tannens forever. Fans quote it for any prank that arrives with a smug lecture, and most people remember it as "You're so gullible".

Spoilers for Back to the FutureShow the scene
In Back to the Future (1985), Biff Tannen is the bully who has leaned on George McFly for decades, and he runs the same routine in two eras. In the 1985 McFly house, and again in the 1955 diner, he browbeats George into doing his work, tells him his shoe is untied, and smacks him on the head when he looks down. He finishes by telling George not to be so gullible. In the film the words are "Don't be so gullible, McFly", and Marty watches. Part II echoes the beat with Biff's grandson Griff.
