A favourite complaint of anti-monarchists is that the Royal family don't have the most robust work-ethic.
Netherlands King, Willem-Alexander, ascended the Dutch throne in 2013 after his mother, Beatrix, abdicated saying it was time for the throne to be held by "a new generation".
So, for the last four years, Willem-Alexander has been a full-time monarch, a husband and dad of three girls.
To the delight of his people and the world in general Willem-Alexander has been secretly piloting KLM passenger flights for 21 years. The King revealed he'd regularly flown flights for a subsidiary of the Dutch flag carrier for over two decades, without many knowing.
