George Clooney knows he landed an ace! The actor attended the SeriousFun Children's Network Hosts Gala in NYC on Monday, Mar. 2, where he gave a funny shout-out to his wife, human rights lawyer Amal Alamuddin.

Stars including Meryl Streep, Danny DeVito, Tom Hanks, David Letterman, and more stopped by Lincoln Center to celebrate the philanthropic legacy of the late Paul Newman. Inside the event, the ever-so-dashing Clooney delivered a charming speech, referencing his personal life as he flubbed a few of his lines.

The Monuments Men director first recognized Newman's charitable work after he started the Hole in the Wall Gang camp in 1988, for children battling serious illnesses so that they "can kick back, and, as he said, 'raise a little hell.'" Clooney then shared how SeriousFun Children's Network has served hundreds of thousands of people, stumbling over the number of countries it has actually reached.

"Since 1988, these camps have [helped] over a half million sick kids and their families from over five, from over 50, not just 500 countries... that would be too many." An observer tells Us that Clooney then made a pensive expression, pondering whether there really were 500 countries.

"There aren't that many... Are there 500 countries?" Clooney mused onstage. "My wife's the smart one."

Indeed, his wife Alamuddin, 37, is an accomplished international lawyer and activist, whose clients have included WikiLeaks founder Julian Assange. She is currently representing Armenia in a high-profile case against Dogu Perincek — chairman of the Turkish Workers Party who was convicted in 2007 for denying that the Armenian genocide occurred.

During World War I, the Ottoman Turks murdered more than 1.5 million people from the years 1915 to 1923. Turkey has since argued that the number of deaths has been exaggerated, denying that it was even a genocide.

Us Weekly exclusively revealed last week that she and Clooney are currently renovating their mansion in Berkshire, England and including a "fireproof, bombproof, and attack-resistant" panic room. The insider explained to Us that with Alamuddin's "high-profile clients in controversial cases," she has felt the need to be secure.

Given her current schedule, the London-based barrister did not accompany her husband to the event on Monday. However, she attended the 2015 Golden Globes with him this past January, where cameras showed her appearing bored and less-than-amused by the Hollywood fanfare — but nevertheless movie star gorgeous in a one-shouldered gown by Dior Haute Couture.
