"Towel Heads"

Recently I received a warning about the use of this
politically incorrect term.

Please try to pay attention.

We have been informed that the Islamic terrorists do not
like to be called "Towel Heads" since the item they wear on their heads is  actually a small folded sheet.

Therefore, from this point forward, please refer to them as
"little sheet heads."

Thank you for your support on this delicate matter.
