Oliver was always a little different from other Chimpanzees.

"You could send him on chores. He would take the wheelbarrow and empty the hay and straw from the stalls. And when it was time to feed the dogs, he would get the pans, and mix the dog food for me. I'd get it ready and he'd mix it. This guy, Oliver, he enjoyed sitting down at night and having a drink, and watching television. He'd mix his own. He'd pour a shot of whiskey and put some Seven-Up in there, stir it and drink it,'' Janet Berger recalled.
