A German woman jumped over a fence into the polar bear enclosure during feeding time and was bitten several times by one of the bears.
The brave keepers eventually managed to push the bear away and pull the woman to safety.
She was bitten by one of the four older polar bears in the enclosure and not by the famous Knut, who took Germany by storm as a cub after he was hand-raised by a keeper.
It is not known why the woman pulled the dangerous stunt but she initially appeared to be elated as she swam towards a bear in the enclosure.
I bet she wasn't elated when the bear started to eat her. She wins the stupid award for the day. You can see more pictures here.
