Vonnegut

Listen, the bird left his cage.

Wiki:
Kurt Vonnegut, Jr. (November 11, 1922 – April 11, 2007) (pronounced [ˈvɑ.nə.gət]) was an American novelist known for works blending satire, black comedy, and science fiction, such as Slaughterhouse-Five (1969), Cat's Cradle (1963), and Breakfast of Champions (1973).
Vonnegut reportedly smoked Pall Mall cigarettes, unfiltered, which he claimed is a "classy way to commit suicide."

I see that in Sweden, the label cynical is sometimes put on him. He was not.

...last sentence of "Slaughterhouse 5", the bird asks "Poo-tee-weet?"
