U.S. President George W. Bush writes a note to Secretary of State Condoleezza Rice during a Security Council meeting at the 2005 World Summit and 60th General Assembly of the United Nations in New York September 14, 2005.
To be fair, and as Snopes points out, he's wise to ask Condoleeza Rice, someone with more experience of U.N. meetings, whether it was possible for him to just get up and go to the bathroom. You can't stand up in the middle of a meeting and say "Back in a minute Kofi, gotta go drain the lizard".
