"All Er Nuthin'" is a tune from the musical play Oklahoma!, written by composer Richard Rodgers and lyricist Oscar Hammerstein II. This song is near the end of the musical, where the secondary characters Will Parker and Ado Annie Carnes decide to get married. Will is wary because he knows Ado is the girl who can't say no (to advances by suitors). In this song he essentially asks for a promise of fidelity from Annie, who agrees to be faithful to him. After Annie suggests a future child in this duet: Will: "He'd better look a lot like me! "Ado Annie: "The spitt'n' image! "
