Boris Yeltsin was making a presidential visit to Washington in 1995 when he was found one night outside the White House dressed only in his underpants. He explained in a slurred voice to US secret service agents that he was trying to hail a cab so he could go and buy a pizza. The following night he was discovered by a guard, who thought he was an intruder, wandering drunkenly around the basement of his official residence.
