Bush almost places the Queen in the 18th century:

Bush noted the queen’s long history of dealing with successive American governments, just barely stopping himself before dating her to 1776, the year the 13 British colonies declared their independence from Britain.

Elizabeth has occupied the British throne for 55 years and is 81.

"The American people are proud to welcome your majesty back to the United States, a nation you’ve come to know very well. After all you’ve dined with 10 U.S. presidents. You’ve helped our nation celebrate its bicentennial in 17 — in 1976," Bush said.

Bush looked at the queen sheepishly. She peered back at him from beneath her black and white hat.

"She gave me a look that only a mother could give a child," Bush said as the crowd burst into laughter.
