Comin' Thro' The Rye - The Catcher in The Rye

The title of the book The Catcher in the Rye comes from the poem's name. Holden Caulfield, the protagonist, misinterprets a part of this poem to mean "if a body catch a body" rather than "if a body meet a body." He keeps picturing children playing in a field of rye near the edge of a cliff, and him catching them when they start to fall off.
