President George W. Bush lauded Queen Elizabeth II and her country as allies in the fight against terrorism, but also committed a verbal gaffe that implied that the monarch was much older than her 81 years during a ceremony on the White House’s south lawn.

After pointing out Queen Elizabeth II had dined with 10 U.S. presidents, Bush said she helped America celebrate its 200th birthday in “177 … 1976,” which drew laughter from the crowd of 7,000 invited guests.
