Clinton had received notice of a major predawn security alarm when Secret Service agents discovered [Russian President Boris] Yeltsin alone on Pennsylvania Avenue, dead drunk, clad in his underwear, yelling for a taxi. Yeltsin slurred his words in a loud argument with the baffled agents. He did not want to go back into Blair House, where he was staying. He wanted a taxi to go out for pizza. I asked what became of the standoff. ‘Well,’ the president said, shrugging, ‘he got his pizza.’”
