Inspired by a 1969 Bob Fosse Routine called “Mexican Breakfast,” this music video features Beyoncé lip-synching and dancing to the track alongside two other women. The video is shot in black and white and gave birth to the iconic “Single Ladies” hand flip move. This consists of flipping your hand back forwards and backward to indicate that you do not have a ring on your finger, as you are a “single lady.” Although, originally, it was thought that the video for “If I Were A Boy,” which featured a true storyline and a higher budget, would be the higher profile of the two, “Single Ladies” became both Beyoncé’s most famous song, and music video, airing across the world on MTV.
