A group of three year olds were recorded arguing over the weather at the Room To Bloom Children's Center in Harrison, Arkansas, last week.
Pharmacist Tara Willmott uploaded the clip to Facebook
on 17 September and it has now gone viral, having been watched around one million times on her page and reaching the top of r/video on Reddit.
The video shows a young boy, identified as "Ty", and a girl arguing over whether it is sprinkling or raining outside.
The pair engage in a passionate debate, which even turns physical at times.
At one point young Ty argues simply: "No, you're pretty and you're not real. Im real."
The discussion comes to an end though when the young girl in green taps Ty on the chest while making her point.
His reaction? "You poked my heart"
It then all becomes too much for Ty and the debate, and the video, promptly ends.
Fear not though, the pair appear to have now made up with pictures on Facebook showing the two girls and Ty enjoying a big hug.
BuzzFeed has reached out to Willmott to find out more about her video.
