Who is Will Robinson?
Ah, showing our youth, are we? ;^)
Will Robinson was the youngest boy in the spacefaring "Space Family Robinson" on the old TV show, Lost in Space. The family assigned a big, clunky robot to follow Will around and protect him as they were all wandering around on this lost world on which their spaceship had crashed. Whenever danger loomed, the big, clunky robot's radar antennae would twirl, its vacuum-cleaner-hose arms would thrash the air, and its mechanical voice would blurt out the warning I quoted. It's a kind of pop-cultural reference for Boomers.
