In James Dickey's 1970 novel Deliverance and its 1972 film adaptation, a character suffers from duck ague before shooting a wild deer, after which another character describes the phenomenon, saying "Hell, I've known tournament archers, damn good shots, never out of the five ring. Draw down on a live animal, they get buck ague."[5]
In the final scene of the 1951 film Fort Worth, one character tells another, "Now don't get buck ague."
