Sad/sweet bit of Muppet trivia:

[sl8]

The scene features Jerry Nelson, long affiliated with the Muppets, and his daughter, Christine. Christine aspired to be an actor and, unfortunately, was afflicted with cystic fibrosis. Jim Henson cast her in The Great Muppet Caper.

There's a running gag thoughout the movie that Kermit (the frog) and Fozzie (the bear) are actually identical twins. They (apparently) look so much alike, that people can't tell them apart unless Fozzie is wearing his hat.

Christine Nelson was born to Jacquie and Jerry Nelson in New York in 1960. Throughout her short life, Christine battled cystic fibrosis, a disease of the exocrine glands which caused numerous lung infections and other illnesses. Her mother, Jacquie, made a career in the fashion world. Her father, Jerry, is known for his work with Jim Henson and The Muppets, and passed his performer's passion on to Christine, who aspired to become an actress after completing high school. After going to many public schools in New York and Connecticut, she attended Rye Country Day School, a prestigious private school with a strong focus on stage and drama, and briefly attended college at Emerson College in Boston, MA but was forced to withdraw because of her illness. She met and became friends with Jim Henson and The Muppets as well as many cast members of Saturday Night Live (1975), such as Gilda Radner, John Belushi and Chevy Chase. In 1981, she won a small speaking part in The Great Muppet Caper (1981), as the girl who said, "Look Dad, there's a bear!", to which her companion, played by real-life dad, Jerry, replied, "No Christine, that's a frog...bears wear hats!" Christine, after fighting her illness, valiantly, for over two decades, passed away in September, 1982.
