Australia's Howard campaign caught distributing fake leaflets playing on anti-Muslim sentiments

"Bogus flyers from a fake organisation called the Islamic Australia Federation were distributed through the letterboxes of voters in a marginal seat, claiming the Labor opposition sympathised with Islamic terrorists.
...A team of Labor officials found five men posting the clumsily printed flyers - the phrase Allah Akbar, God is Great, had been misspelled as Ala Akba - through letterboxes in the early hours of the morning."

Lesson: In order not to be caught playing dirty tricks to one's political opponents now, one must know how to spell 'Allah Akbar'.
