There are times when the stock markets are selling at a steep discount. At such times, Buffett says he feels like an oversexed guy in a whorehouse, and his main complaint is that he doesn't have ENOUGH money to buy ALL the bargains he can see. At other times, when he sees a stock he really likes (like Coke), he'll simply buy as much as he can.
