The lad was fast asleep with the curtains drawn when his joker sibling snuck in quietly with a mouse trap in hand.
The prankster turned the light on, set his camera up and tip-toed over to his brother to place the rodent-killing device over his privates.
And it didn’t go down well.
In cringeworthy video, his poor brother gasps in pain and wriggles around holding his crotch.
When he finally manages to prize the contraption from his privates he begs his mum for help but she casually shrugs it off telling him to just put a plaster on it.
The clip – filmed in America – has racked up thousands of hits in only a day. and viewers loved what they saw.
One YouTube user wrote: “Wow. My balls hurt watching it and I’m a girl and don’t have balls!”
Another commented: “He was so calm. I think I’d have thrown him out the window.”
And a third added: “Shave his hair off as revenge!”
But this isn’t the first prank to amuse viewers this week.
