British dad Ben might not be set for the best Father's Day present in a couple of weeks' time, after he pulled this brutal - but hilarious - prank on his son, and put it all on the internet.
In the video available above, we see Ben's son fast asleep. He's then woken up by his dad, who tells him that he has slept all weekend and must quickly get ready to go to school.
The poor kid looks a bit bemused but starts asking for cereal for breakfast.
What happened next has made the video go viral since Ben posted it up on Twitter - although we're not sure his son will be best pleased about it all... Check out the video above to see what happened next for yourself!
