Former President Barack Obama left a group of children in fits of giggles as he pulled a stunt on them during a visit to a childcare center in New York on Saturday.

Obama and Mayor Zohran Mamdani read to preschoolers and led a sing-along during the visit, and did not take questions after their appearance.

While at the Learning Through Play Pre-K school, Obama and Mamdani read the book 'Alone and Together' to the children and led a sing-along of 'The Wheels on the Bus.' 

After sitting on chairs during the reading, the two sat down on the floor to play out a key theme in the 'Alone and Together' book.

'Remember the book said, we are strong together,' Obama inquired of the children.

'So you're going to have to all help me get up,' the former president continued amid shrieks and laughter from the young attendees, before adding 'Because I'm old.'

Obama, now 64, served as president from 2009 to 2017, long before most of his Saturday crowd were born.

The 44th president offered to be a sounding board for Mamdani, 34, whose star power, youth, and progressive agenda have made him stand out in Democratic politics.

Obama placed second in a recent Daily Mail/JL Partners Poll asking readers who they believed was the most powerful man in America, while Mamdani ranked 16th. Current President Donald Trump topped the list.

The Saturday visit came as the Mamdani mayoral administration pushed its policy plan of free, universal childcare in the Big Apple.

In an interview that aired Sunday on NBC News, Mamdani told Meet the Press moderator Kirsten Welker that his efforts 'are not only providing free childcare for every three-year-old in this city, we're now doing it for two-year-olds as well.'

'And by the end of our first term, we will see every single two-year-old receiving free childcare across the five boroughs of New York City,' Mamdani also noted.

If elected to a second term, Mamdani also pledged to pursue providing free childcare to 'one-year-olds and those from six weeks and above.'

'We've always said over the course of the campaign, we would deliver it for New Yorkers from the ages of six weeks to five years,' Mamdani also told Welker. 

'We're talking about $20,000 a year that a family won't have to shell out for childcare any longer, because they know they can afford to raise their kid in the city they love,' the Mayor added to sell his idea.
