Bit tangental, but did anyone see the proggie on chimps (iirc) a while back on Discovery? Bunch of stupid monkeys nicking drinks from people at a beach resort, getting hammer drunk and falling over themselves. Some astute individual got the idea to study the monkeys (read that drink and watch monkeys drink on someone else's dime), and claimed that the monkeys in this area drank to excess, drank a little, or abstained entirely in the same percentages as the group of humans they tested.
