Will & Jack: Tell me he's lazy, tell me he's slow. Tell me I'm crazy, maybe I know. Can't help lovin' that man of mine.
These are lyrics from the Barbra Streisand number "Can't Help Lovin' That Man Of Mine." Although Barbara sang the song, as have many others, it's originally from the musical Showboat, written by Jerome Kern and Oscar Hammerstein II, sung by the tragic character Julie, and originally produced in 1927.
