You!
The shortest poem (ever?) by Gavin Ewart (1916-1995), a poet, an advertising copywriter, and an irreverent wit who published many volumes of poetry during his life, mainly of light, comic, satiric, and erotic verse. However, he was equally adept with sonnets as limericks, clerihews, and occasional verses.
Select titles include Pleasures of the Flesh (1966), Or Where a Young Penguin Lies Screaming (1977), All my Little Ones (1978), More Little Ones (1982). There are also a number of collections spanning his 50 year career.
