“Catch-22” is a reworking of “The Fateful Adventures of the Good Soldier Švejk in the World War” by Jaroslav Hašek - Joseph Heller himself once said that he would never have written “Catch-22” had he not read “Švejk” to begin with; it was the inspiration for his book.
Interesting. I’d never read or heard that before. Enjoy the pivo.
