Actress and comedian Amy Schumer took a moment from her self-proclaimed “newly famous” lifestyle to pop inside the Beacon Theatre in New York on Monday night for a 30-minute stand-up set that roused the audience, thanks to Kardashian- and Jenner-related jokes and, not surprisingly, plenty of self-deprecation. Dolled up in a little white dress, Schumer, who admitted to not knowing what a thigh gap was, opened a fundraising show for Jerry Seinfeld, who later took the stage and delivered an unforgettable performance of his own.

It wasn’t just another comedy show, though. The two funny stars were both on hand to celebrate 15 years of Baby Buggy, the organization that Seinfeld’s wife and InStyle's go-to food guru, Jessica Seinfeld, founded in 2001 in an effort to help lift children and families out of poverty. The evening raised an impressive $1.975 million and to welcome her guests, Seinfeld delivered an emotional speech that highlighted just how successful the charity has become. “I thought it was going to be this crazy, free garage sale 15 years ago and that would be it. I had no idea that I would continue, that we would build this unbelievable team that would—it’s really kind of unbelievable,” she told InStyle.

The beauty dazzled in a floral print J.W. Anderson dress that she slipped into just 45 minutes before the show. “He’s so cool and I love wearing designers that don’t have an ad budget and don’t have tons of support. I am going to wave his flag all night,” she said of her look moments before hugging friend and Baby Buggy board member Ali Wentworth (in a design by Veronica Beard, also a Baby Buggy board member). So does Wentworth have a favorite memory from working with Seinfeld on her team? “Jessica and I once took our kids to the warehouse and it was a great moment because we were saying to our kids, 'This is what Baby Buggy is.' It’s all about getting your hands into it because they’re the next generation and they gotta give back.”

Meanwhile, supportive stars like Drew Barrymore, Michael Strahan, and Victoria Justice (below, left) arrived for the comedic performance. Justice, who donned a skintight blue H&M dress with a Balmain x H&M gold choker, matched with her sister, Madison Grace, for the occasion. “That kind of happened unintentionally,” she told InStyle. “She steals my things all the time. She doesn’t ask me. I get mad at her sometimes. I should have like a passcode that you have to punch to get in.”

Jokes aside, Justice was there to support Baby Buggy. “It’s amazing what they’re doing for families in need and it’s incredible. And then of course just a night to laugh and have a good time, and Jerry Seinfeld’s a legend and I love watching Seinfeld reruns—he’s hilarious. I love that [Amy] is a woman who has creative control of what she does, and she writes and she’s really talented,” she added.

Strahan shared similar sentiments. “I think that what they do to make sure that parents have what they need for their kids is absolutely amazing because I was a young parent before,” he said. So what advice does he have for new parents everywhere? “There is no manual, but remember that what that child learns, the way that they learn how to love and how to build relationships and community, all those things they learn from you. And that’s the great responsibility. Take it seriously, but at the same time, make sure that you have fun with your kids and enjoy the process.”
