In Sweden there is a rule, that all citizens can become Prime Minister, except for the one person who is CEO of IKEA.

Because they know, he would spend 4 years just assembling the cabinet.

@randahl There is a story (almost certainly apocryphal)* about a Prime Minister who wanted his obituary to refer to him as a "cabinet maker" so that it looked like he'd actually done something useful with his life.

* and, upon googling to see if it's apocryphal, it turns out to also have been said about other PMs than I've heard it said about... so forget the "almost"...)
