Catch-22 Chapter 18: The Soldier Who Saw Everything Twice
Yossarian flashes back to his days as a private when he first ditched physical education by escaping to the hospital. When doctors finally assess Yossarian as healthy, Yossarian adopts the dementia experienced by a roommate who sees double. Yossarian spends Thanksgiving in the hospital, and the following year, he spends his Thanksgiving with Lieutenant Scheisskopf's wife, having sex and debating the benevolence of a non-existent God. Before leaving the hospital, Yossarian impersonates a dying soldier, Giuseppe, for some grief-stricken visiting relatives.
