Miss Piggy is a Muppet character who was primarily played by Frank Oz on The Muppet Show. In 2001, Eric Jacobson began performing the role, although Oz did not officially retire until 2002. Miss Piggy began as a minor character in The Muppet Show TV series, but gradually developed into one of the central characters of the show. She is a pig who is convinced she is destined for stardom, and nothing is going to stand in her way. She presents a public face which is the essence of feminine charm, but can instantly fly into a violent rage whenever she thinks she has been insulted or thwarted. Kermit the Frog has learned this all too well, since he is the usual target for her karate chops. When she isn't sending him flying through the air, she is often smothering him in (usually unwanted) kisses.
