Here’s a rundown of the best zingers at the Democratic National Convention on Tuesday night

Forty-four brought the house down with his joke about Trump’s puzzling obsession with crowd sizes at Harris rallies.

“There’s the childish nicknames,” Obama said. “The crazy conspiracy theories. This weird obsession with crowd sizes.”

The former president, Nobel Peace Prize winner, best-selling author and constitutional law scholar moved his hands closer together and back apart as he spoke, in what looked to many chuckling delegates like a reference to Marco Rubio’s infamous reference in 2016 to Trump’s “small hands.”

“It just goes on, and on, and on,” Obama said. “The other day I heard someone compare Trump to the neighbor who keeps running his leaf blower outside your window every minute of every day. Now, from a neighbor, that’s exhausting. From a president, it’s just dangerous.”

Obama’s jokes were bipartisan, albeit with less edge when he dinged Walz, a self-effacing former teacher and school principal from the key swing state of Minnesota, for his sartorial choices.

“You can tell those flannel shirts he wears don’t come from some political consultant,” Obama said. “They come from his closet, and they have been through some stuff. They have been through some stuff. That’s right.”

As Obama spoke, the cameras cut to Walz’s wife, Gwen, who clapped enthusiastically from her seat and appeared to mouth, “that’s right.”

At another point in his speech, Obama harkened back to his 2004 remarks at the DNC in Boston, when he introduced himself to the country with an electrifying monologue calling for unity and praising the nation as a haven for “a skinny kid with a funny name,” such as his younger self.

On Tuesday night, Obama intoned, “I am feeling hopeful -- because this convention has always been pretty good to kids with funny names who believe in a country where everything is possible.”

The line also served as another veiled dig at Trump, who’s taken to purposefully mispronouncing Harris’s first name, as have many of his supporters.

Michelle Obama drew sustained applause when she praised Harris, who’s seeking to become the first Black woman to win the presidency, landing a palpable hit on one of Trump’s familiar talking points.

“I want to know, who’s going to tell him that the job he’s currently seeking might just be one of those Black jobs,” Michelle Obama said.

Trump sparked outrage in June when he asserted that migrants coming into the US across the southern border are taking “Black jobs,” a comment that generated an avalanche of online memes poking fun at the notion of unspecified jobs designated for people of color.

“It’s his same old con,” Michelle Obama said Tuesday. “His same old con. Doubling down on ugly, misogynistic, racist lies as a substitute for real ideas and solutions that will actually make people’s lives better.”

Emhoff delighted the crowd with an anecdote about his first date with Harris, as well as some on-the-nose Gen-X pop cultural references befitting the worldly 59-year-old.

He said his fantasy football team’s called Nirvana, “yes, after the band!”

And he had spectators enthralled as he recounted his first phone conversation with Harris, at the time a rising Democrat who would later become his soulmate. Following the phone call, Emhoff told the crowd, he left Harris a rambling voicemail that she plays for him every year on their anniversary.

“I love that laugh,” he said affectionately, a rebuke to Trump’s uncouth criticism of Harris’ laughter.
