Hundreds gathered for President George H.W. Bush’s state funeral at the Washington National Cathedral today.

The ceremony at the cathedral, the nexus of state funerals, capped three days of remembrance in the nation’s capitol by dignitaries and ordinary citizens as they honored the Republican president who oversaw the post-Cold War transition and led a successful Gulf War, only to lose re-election in a generational shift to Democrat Bill Clinton in 1992.

More than a dozen world leaders were in attendance, including Prince Charles and Angela Merkel.

Lighter moments of Bush 41's funeral

Grey Goose delivery

George W. Bush delivered a eulogy from the heart that was sprinkled with humorous anecdotes about his dad.

With a twinkle in his eye, 43 told about a special delivery for his father when he was in the hospital years ago.

"In his 90s, he took great delight when his closest pal, James A. Baker, smuggled a bottle of Grey Goose vodka into his hospital room. Apparently,it paired well with the steak he had delivered from Morton's," the 43rd president said.

Sully in the spotlight

Rev. Russell Levenson of St. Martin's Episcopal Church in Houston drew laughter when he joked that Sully, Bush 41's service dog, "has gotten more press than the president in recent days."

Rev. Levenson also mentioned how former first lady Barbara Bush, who passed away in April, sometimes reminded him that his sermons would go on just a bit too long.

An emotional eulogy by George W. Bush

11:20 a.m. In his eulogy, George W. Bush, the oldest son of George H.W. Bush, remembered his father as a man who believed in the importance of public service, a loving family man and a man who always looked for the best in people.

George W. Bush recited a quote,"Die young, as late as possible," before sharing stories of his father later in life. At 85, George W. Bush said, his father took his 300-horsepower boat out in the open Atlantic as the Secret Service boats struggled to keep up behind.

At 90, George H.W. Bush went parachuting. And in his 90s, George W. Bush said, his father's closest friend, James Baker, snuck in a bottle of vodka into his hospital room to go with his dinner.

George W. Bush remembered his father as a man who loved to laugh, especially at himself, "and placed great value in a great joke."

Before his father died, George W. Bush remembered calling his dad and telling him, "I love you. You've been a wonderful father." To which his father replied, I love you, too.

"Those were the last words he spoke on earth," George W. Bush said.

"We're going to miss you. Your decency, sincerity, and kind soul will stay with us forever," George W. Bush said. "So through our tears let us know the blessings of knowing and loving you, a great and noble man. The best father a son or daughter could have." Bush stopped for a minute, fighting back tears. "And in our grief, let us smile knowing that Dad is hugging Robin and holding Mom's hand again."

Remembering George H.W. Bush

11:12 a.m. Former Senator Alan K. Simpson, a friend of George H.W. Bush, said "the most decent and honorable person I ever met was George Bush." Simpson said Bush loved jokes, but could never remember a punchline. The punchline for Bush, Simpson said, is "you would have wanted him on your side. He never lost his sense of humor. Humor is the universal solvent of the abrasive elements of life. He never hated anyone. He knew what his mother and my mother always knew: hatred corrodes the container it's carried in."

10:55 a.m. Canadian Prime Minister Brian Mulroney said of George H.W. Bush, "I believe it will be said that no occupant of the Oval Office was more courageous, more principled and more honorable than George Herbert Walker Bush."

10:35 a.m. Jon Meacham, George H.W. Bush’s biographer, said Bush’s life code was to “tell the truth, don’t blame people, be strong, do your best, try hard, forgive, and stay the course. And that was and is the most American of creeds.”

"To him, his life was no longer his own. There were always more missions to undertake, more lives to touch and more live to give," Meacham said.

Members of the Harris County District Attorney's Office are wearing their unique socks today in honor of George H.W. Bush.
