This might be the cutest thing you see all day.
A boy's hilarious reaction to a set of automatic doors was caught on camera in a now-viral video, posted online by his dad.
"Took our son to the grocery store and let him walk around for the first time, he was blown away by the automatic doors," Abraham Vargas wrote on YouTube.
The clip shows the boy staring at the doors sliding open and shut on their own, his mouth hanging wide in amazement. He shrieks as he runs to another set of doors, only to find them do the same thing.
Vargas told TODAY.com that the clip was taken on Saturday at the Kroger supermarket where the family lives in Dallas, Texas. His son, Azrael, is 21 months old and usually rides in the cart, but that day, his parents let him walk around on his own.
"I thought it was funny," he said of watching his son's reaction to the doors. "He's just learning to talk and he knows how to say some words. He shouted, 'Dang!' That's what you can hear him saying in the video."
The clip has already been viewed nearly half a million times. The proud dad might have a YouTube star on his hands — other videos he's posted show his son twerking, crying over the birthday song, and preparing for an earthquake, according to Vargas' hilarious voice-overs.
But he never expected this one to be so popular: "I didn't know it was going to blow up like this," Vargas said. "It's all kind of crazy."
