John Sigvard "Ole" Olsen (November 6, 1892 – January 26, 1963) and Harold Ogden "Chic" Johnson (March 5, 1891 – February 26, 1962) were American comedians of vaudeville, radio, the Broadway stage, motion pictures and television. Their shows were noted for their crazy blackout gags and orchestrated mayhem ("anything can happen, and it probably will"). Their most famous production was the play (and later movie) Hellzapoppin.
Comedy teams traditionally had a straight man and a stooge. However, Olsen and Johnson both took on the comic role, goodnaturedly chuckling their way through the steady barrage of gunshots, explosions, props plummeting to earth, intrusions from other performers, and input from the audience.
