Foi Bush quem escreveu o cartaz?

A Reuters criou uma legenda genial para essa foto acima:

President George W. Bush and Office of Management and Budget Director Joshua Bolton (C) talk to conferees, above a misspelled sign, at the White House Conference on the Economy in Washington, December 16, 2004. The White House went all out to showcase the advantages of U.S. President George W. Bush's ambitious financial agenda this week, but in the end the "challenges" proved too much. The word "challenges" -- a main theme of a two-day White House economic conference that ended on Thursday -- was misspelled on a large television monitor that stood in front of Bush during a panel discussion.
