“Something rotten in the cotton”

“Something (is) rotten in the cotton” is a Southern expression meaning that something is wrong. U.S. president Lyndon B. Johnson (1908-1973) is credited with saying it.
 
“Something rotten in the cotton” appears in print by at least 1961, when the line was used in the play Purlie Victorious by Ossie Davis.
