The Iranian flag has the phrase 'Allahu Akbar' (God is great) inscribed 22 times round its border, 11 in green and 11 in red. The number was chosen because the Islamic Revolution in Iran took place on the 22nd day of the 11th month in the Iranian calendar.
The Iranian calendar is based on the Zodiac, with the year beginning on March 21.
Iran has no laws against money-laundering.
At weddings in Iran, it is traditional for the bride and groom to lick honey off each other's fingers to ensure their life together starts sweetly. This did not have the desired effect at a wedding in the city of Qazvin in December 2001 when a 28-year-old bridegroom was reported to have choked to death on one of his new wife's false fingernails.
In 2008, an attempt in Iran bid to beat the record for the world's biggest sandwich failed when the impatient crowd ate the mega-snack before it was measured.
