He didn’t want a pool for his kid to play in - he also wanted a pool for himself.
When his wife asked him to buy a paddling pool for his son to cool down in the British weather - he was annoyed that a paddling pool wouldn’t be big enough for him to use.
So calling on the local skip bins for hire, he lined his new driveway pool with a tarp, filled it with water - and waited for his wife to discover their new outdoor feature.
