Normally, a ballet performance can elicit claps and even cheers and bravos, but it's not very often that ballerinas get laughs and chuckles from those watching. However, this performance, at the Vienna State Opera in Austria, is a little different. The video shows part of a famous ballet from the 1950s, choreographed by a former New York City Ballet ballet master, Jerome Robbins. The whole ballet, titled "The Concert (or The Perils of Everybody)," features gags, pranks, and over-the-top caricatures, set to the music of Chopin. Since its premiere in 1958 in New York, it has also been performed in London, Washington, DC, and Seattle, among other places.
