Nininbaori (二人羽織り) is a Japanese comedic act where two people wear the same large coat (haori) and pretend to be one (hunchbacked) person. One person is the "face" and the other is the "arms". Humor arises from the arms never being coordinated with the face.
This type of skit is considered a staple of Japanese comedy, traditional and modern, and is commonly used as a part of comedy shows; both live stage performances and Owarai (television comedy).
