He thought it was just a bit of fun and expected it to end in smiles.
But Delhi student Prateek Verma got much more than he bargained for when he told his dad his girlfriend was pregnant — and filmed it.
Sunder Verma reacted angrily, punching, kicking and slapping his clearly shocked son.
But he wasn't shocked enough to stop him uploading the clip to YouTube, via his SocioCatastropheTV account.
Prateek starts by explaining the prank to his audience as he waits for his father to come home.
When Sunder comes home, Prateek tells his dad he needs to talk.
The pair sit down, Sunder clearly concerned about what his son has to say.
With his father now lying down, Prateek drops the bomb.
His father takes a few seconds to digest the information, before lashing out at his son with a kick.
He then gets up and immediately starts swinging punches, as Prateek cowers.
More kicks are unleashed...
...then more punches...
... and then two hard slaps. Sunder is clearly livid.
As he picks up a nearby bottle and prepares to use it, Prateek reveals it is all just a prank.
He moves in and tries to hug his father to say sorry...
...before gesturing to the camera to cut as he dad storms off.
More than 1.1 million people have watched the video on YouTube.
