In the 1800s in Spain, king Ferdinand VII, was famously keen on playing billiards while being a really bad player. His opponents were known to, not only play badly, but play so that he would get easy positions to shoot.

"Así se las ponían a Fernando VII" is even nowadays a popular -though not that widely used today- expression to tell someone the task in front of them is an easy one nobody can fail.
