It's a prank Bart Simpson would be proud of. After several controversial stunts, including trying to flog knuckle-dusters outside a Bulldogs rugby league game and approaching the Prime Minister, John Howard, with an over-sized axe, ABC TV's Chaser boys have struck again.

The pranksters pulled off a stunt at Sydney Airport on Wednesday which saw Virgin Blue staff make a "final boarding call" announcement for five late passengers, including one which sounded suspiciously like Mr Al Qaeda and another which sounded like Mr Terrorist.

Less than a week since UK and US authorities foiled a plot to blow-up mid-air trans-Atlantic flights, The Chaser's War on Everything decided to test domestic airport security in the most "puerile" way possible.
