Accepted Answer

My boss is off his rocker. He wants me to be at work early the morning after the dance. People have been using this phrase since the mid-1800s. "Rocker" in this idiom refers to a rocking chair, and there are at least two theories about how being "off your rocker" came to mean "crazy." If you fell off your rocking chair, it was a sign of being mentally unstable. "Rockers" are also the two curved pieces upon which the chair rocks.
