The news that you are going to become a sister or brother is big news, no matter your age.
And then there are those, like almost 3-year-old Kathryn Williams, who just can't hold it in.
In an adorable video captured on YouTube, little Kathryn is told by her dad that she is going to be a big sister. The look on her face is priceless, as she responds to her dad in a whisper, with impeccable comedic timing, "I farted!"
Williams' dad dissolves into laughter, and you will too.
As one You Tube commenter said: "21st birthday video right here."
