Personality is a song written by Johnny Burke (lyrics) and Jimmy Van Heusen for Dorothy Lamour to perform in the 1946 film Road to Utopia. The song became a number one Billboard hit for Johnny Mercer in 1946 (Lamour was between record contracts at the time of the film's release so she did not record the song until years later).
Forty years later the song was rewritten as a commercial jingle for Wesson cooking oil and sung by Florence Henderson as "Wessonality".
