Haha reminds me of this, i'm sure on the actual episode they tell a story about how a small heard of them got drunk on fermemnted apples that had been under the snow all winter and then wondered into town and destroyed some shops.
All mamals have a drive to get drunk In India they have problems with drunk apes and appently a drunk elephant cha be a bit of a handful and you cna sometimes get whole herds head in to town and cause mayhem.
