WATCH: Robbie Keane dupes his own son with the oldest prank in the book

Robbie Keane either enjoyed this way too much or exactly the right amount... there's no in between.

No matter how much technology improves, there are certain things that will never die out. When kids are playing alongside a VR version of a veteran Marco Verratti in their own living room, they'll still go outside and have a jumpers for goalposts kickabout on the green. When they finally develop hangover-proof alcohol, people will still be calling in sick for work the morning after a big match. When information starts being beamed directly into people's brains through some sort of cloud-based system, people will still buy newspapers... maybe. Well no matter what happens to the human race from here to eternity, as long as we're all still breathing, we'll still be trying to prank our fellow inhabitants of planet Earth. Republic of Ireland legend Robbie Keane busted out the classic coin-in-the-bottle 'magic' trick on his son recently. He uploaded the entire prank to his social media accounts and because he's such a well-known sports star, millions have now witnessed him fooling his son. https://www.instagram.com/p/BSiyaLnh7ZJ/?taken-by=robbiekeane&hl=en
