“Danger, Will Robinson!” is a catchphrase from the 1960s’ American television series Lost in Space spoken by voice actor Dick Tufeld. The Robot, acting as a surrogate guardian, says this to young Will Robinson when the boy is unaware of an impending threat. In everyday use, the phrase warns someone that they are about to make a mistake or that they are overlooking something. The phrase is also used in hacker culture.
When given in person, the vocal klaxon is sometimes accompanied by oscillation of the speaker's arms, parodying the Robot's body language.
Despite the popularity of the phrase, it was only said once on the show. This was during episode 11 of season 3 "The Deadliest of the Species". The Robot gave warnings intermittently to Will and the other crew members of the Jupiter 2, in the form of the expressions "Warning!" and "Danger!"
