Former President Bill Clinton had a memorable moment at the Democratic National Convention on Wednesday, Aug. 21, while speaking about Vice President Kamala Harris and Minnesota Gov. Tim Walz‘s vision for the future — and  Donald Trump‘s age.

Clinton, who turned 78 on Aug. 19, joked about his own age during his remarks before adding: “The only personal vanity that I want to assert is that I’m still younger than Donald Trump,”

Trump, also 78, was born in June.

Elsewhere in his remarks, Clinton also alluded to Trump’s seeming obsession with crowd size, adding to a joke made by Barack Obama on Tuesday night.

“So, we’ve got to ask ourselves the question: Do you want to build a strong economy from the bottom, up, and the middle, out — or do you want to spend the next four years talking about crowd size?” Clinton asked.

The 2024 election, Clinton said, was a choice between Harris — who he said “will ease our fears” — and “the other guy, who’s proved, even more than the first go-around, that he’s about me, myself and I.”

Clinton also urged the audience to listen to Trump’s words when he speaks, saying, “The next time you hear him, don’t count the lies. Count the I’s — his vendettas, his vengeance, his complaints, his conspiracies … he’s like a tenor trying to get his lungs open by singing, ‘me, me, me, me, me.’ ”

“When Kamala Harris is president, every day will begin with you, you, you, you, you,” he added.

Clinton has been helping the Democratic Party rake in cash throughout the 2024 campaign cycle, previously joining Presidents Barack Obama and Joe Biden for a star-studded New York City fundraiser in March, when Biden was still on track to get re-nominated.

When Biden abandoned his reelection bid and backed Harris to take his place on the Democratic ticket, the Clintons quickly followed suit, offering an endorsement of Harris that same afternoon.

“We’ve lived through many ups and downs, but nothing has made us more worried for our country than the threat posed by a second Trump term,” the former first couple said in a statement. “He has promised to be a dictator on day one, and the recent ruling by his servile Supreme Court will only embolden him to further shred the Constitution.”

They continued: “Now is the time to support Kamala Harris and fight with everything we’ve got to elect her. America’s future depends on it.”
