Not the crux of the biscuit.

Hmm, apparently alcohol does impair your judgment after all.

A 31-year-old man who had just woken up from a drunken stupor after falling asleep overnight in a zoo in Estonia tried to offer a polar bear a biscuit - and had his hand bitten off. His screams drew security personnel, who promptly called an ambulance which took the man to hospital in the capital, Tallinn, the Baltic News Service reported.

The unidentified man had passed out after consuming large amounts of alcohol with friends. He woke up in the early hours of Thursday, found the biscuit in his pocket offered it to the bear. Tallinn Zoo manager Mati Kaal, who has worked more than 30 years at the zoo, told BNS that it was the 11th time he had heard of such accidents, although "this is the first hand. In other cases it's been the whole arm."

The eleventh time? Maybe they should put up a sign or something.
