Okay, so we can't top these stories, but my brothers and I are no slouches!
I've partied with a few animals over the years (human and not), but Elephants? My favorite quote:
"No wonder they don't sell beer at the circus. Apparently, elephants like to get wasted. In fact, an outpost of the Indian army in the jungle region of Bagdogra has been under attack ever since a local herd of elephants raided the base in search of food and discovered the soldiers' entire winter rations of rum.
Since then, the pachyderms have regularly raided the base for a drink and have smashed down all defenses put up by the army, including electrified fences and firewalls."
Scott Adams of Dilbert fame has a similar thought.
