There is an old saying that says "dance like nobody is looking". Well, one dad found out that mom's hidden camera was looking - and now the whole world.

According to Rumble Viral's YouTube page, Rujeana, a mother of two children, decided to set up a camera in her living room so that Grandma could see the kiddos doing cute things. But, as you can see in the video above, she got a whole lot more than she bargained for, catching her husband dancing around to a song by pop star Katy Perry.

The dude has some pretty slick moves as he glides across the floor singing the lyrics "Kiss me, k-k-kiss me. Infect me with your love and fill me with your poison". In fact, his moves were so good, we bet nobody even noticed the gigantic spider on the ceiling.

Regardless, the video is proof there are good dads out there. And some of them remember 'the robot'.
