McDonald's Have Bought Out Angry Birds Themed Burgers..

Food colouring may have gone out of fashion, but it seems McDonald's didn't get the memo.

The global food franchise has launched an "Angry Birds" burger range in its restaurants in China, to coincide with the opening of the movie of the same name.

The burgers, featuring either red or green food colouring in the buns, look weirdly inedible, and have been met with mixed opinions from Maccas fans.
