Ha, that made me laugh today, too. I just imagined a wallaby being high and hopping in circles, and I couldn't hold my laughing.
I also saw a film longer time ago, showing parotts who ate plenty of overripe fruits - and got totally drunk. Now there was a jungle full of drunken red parotts doing the strangest sorts of stuff - or at least trying to do so...
And then there were our two dachshounds 25 years ago, one of them loved beer, and even discovered how to throw an open bottle from the table and then drink it on the floor. I don't tell you what a drunken dachshound uses to do when being drunk, just use your imagination and you get an idea that probably is very close to the truth...
