Kindergarten classrooms were filled with very small “old age pensioners” on February 12 when children and teachers across the US dressed up as 100-year-olds to celebrate their 100th day of school.

One little girl called Milan was filmed by her mother, Melony Clark, as she hobbled her way through their apartment block. In the video, she can be heard asking her mom, “Can you help me get to my house, young lady?”

Photos of 100-year-old kindergarteners were shared by their amused parents as they joined the fun.

Some kids used canes, and hobbled around comically, while others looked like they were up for causing mischief. Credit: Instagram/milanakamimi via Storyful
