This is the moment a group of clueless teen siblings are captured on cell phone video attempting to operate an old-time rotary telephone.

In the comical video taken by their father in Clarksville, Arkansas last Wednesday, the kids are shown staring at the foreign device while one attempts to properly dial a number.

When the teen boy wearing the green shirt couldn't seem figure out how to dial a number properly, his brother, sporting sweatpants and no shirt, attempted to take on the challenge.

Their sister in the back is seen trying to assist - telling her brother: 'I know how to do it, I know how to do it!,' as he swats her hand away.

'Well, if I did that, I just called mom,' the teen says in the video, before realizing the call was not successful.

The frustrated teen is then seen throwing the phone on the table before walking off as his sister picks it up for a final failed attempt.

The video had been viewed nearly 900 times since it was posted Wednesday.
