"Not happy, Jan!" was a line delivered by comedian Deborah Kennedy in an Australian television advertisement from the year 2000. Due to the ad's popularity in Australia, the line entered the cultural vernacular as a catch phrase used to express a feeling of discontent. The phrase was co-opted by the unsuccessful 'Not happy, John!' campaign, opposing the re-election of Australian Prime Minister John Howard in the 2004 federal election. The title of the campaign also became the title of a book detailing the negative aspects of the Howard Government.
