- Origin
- The phrase originated in late 19th-century America, possibly tied to rocking chairs symbolizing calm, with falling off implying disruption, as noted in *Harper’s Magazine* (1890s). Its modern use emerged in the early 20th century, with *The Chicago Tribune* (1920s) using it for eccentric behavior. The idiom gained traction in the 1930s, amplified by radio comedies and slang, notably in *The Three Stooges* shorts. Its adoption, primarily in the U.S., stems from its vivid imagery and applicability to oddity, with some use in the U.K. and Australia.
