If you're happy and you know it, clap your hands!
In the age of the internet and social media, even the youngest, tiniest humans can become internet sensations.
One baby has done just that with a video that has gotten over 2 million views, and he isn't even out of the womb yet.
The mother who posted the video, Jen Cardinal, wrote, "At our 14 week ultrasound our baby was clapping, so I sang a song with our doctor as my husband filmed."
You can hear Cardinal singing, "If you're happy and you know it clap your hands," while the baby in the ultrasound clapped his little hands several times.
