When KFC promised viewers of Oprah Winfrey free chicken, some fans thought it was too good to be true.

And they were right, within hours there were queues outside the stores and KFC began to run out of their newly launched grilled chicken meals.
 
Some restaurants even had to employ extra staff to manage the crowds which formed after the show on Wednesday.

KFC bosses say as a result they are currently unable to honor the freebie vouchers which viewers were able to download from Oprah.com

They are asking coupon holders to provide their details and will then mail new vouchers out in stages, hopefully this will calm what some are calling the Chicken Riots of '09.
