"Doc" is just a jealous, bitter, elitist who hates everything. He has no basis for his elitist attitude other than being American and breed to look down on others. He sabotages his relationships on a drink by drink basis, and is said to only be happy when his life is in constant chaos. He loves the smell of fresh cut firewood and spilled whiskey on a wadded up mini dress. He treats his golf clubs with more dignity than anything in his life (even though they may possibly be his most dysfunctional of his relationships) and will side bet anything. He prefers opening up his presents Christmas morning rather than Christmas Eve, follows the teachings of Crash Davis religiously, and hates others that have more than him.
"Greed captures the essence of the evolutionary spirit." -Gordon Gekko
