“Proofread carefully to see if you any words out”

“Proofread carefully to see if you any words out” (minus the word “left”) is a jocular editing one-liner that has been printed in many newspapers and books. “Check to see if you any words out” was printed in the journal College English in 1961. New York (NY) Times “On Language” columnist William Safire (1929-2009) wrote in a 1979 column, “Proofread carefully to see if you any words out.”
 
“Proofread Carefully to See If You Any Words Out” was printed on T-shirts in 1998.
