5-year-old makes secret video on mom's iPad

"I could hear them. (I) just didn't know they were making (videos)," Johnson said in a Facebook comment.

In the clip, you can hear Jordyn, 5, tell her 1-year-old sister, "Syd, move so they can see my stanky leg."

Johnson was so amused by the video, which she said was originally 9 minutes, that she uploaded it to her Facebook page.

The Facebook embed has over 16 million views.
