I saw a squirrel carry an opened beer can up a hollow tree and tried to put it into his den. There must have been some left in it b/c each attempt he got worse in his efforts. After about ten minutes he stopped and laid on his stomach too drunk to move. After about two hours he got enough of his senses back to crawl notice I didn't say hop to a small overhang and creep under it. I got down a short time later and inspected the can which had been bent in the middle and at the crease there was a small opening where he was carrying it spilling its contents into his mouth. There was a little left in the can so I left the rest for last call in case he got enough nerve to try it again!
