Oh, that's funny (and alarming).
In Southern Africa, elephants are very keen on the fruit of the marula tree. They eat it when it is rotting and fermented - i.e. when it has become a powerful liquor by natural process.
And no, you don't want to see a drunken lurching 8-tonne elephant. It's scary. I had to drive off the road for one in Botswana once. But maybe they do it to get cool in the harsh desert heat of the Kalahari?
Mmmh - puts a rather more dubious interpretation on this card altogether. Drunk truck drivers, maybe?
