The end of Davos reminds me of when we had sleepovers as kids. You'd try and stay awake long past your normal bedtime and by the end you'd tend to crack up over anything.

Davos, Switzerland.

You can see that sleep-deprived attitude creeping in at WEF late Friday. People have been hitting the Piano Bar until 5 a.m. and getting up for 9 a.m. sessions. A group of journalists suppressing hilarity after a TV reporter (not Fox) tried to introduce herself to Rupert Murdoch, who refused her and just shook his head violently.

A couple of policeman having snowball fight outside the secure area.

A spirited discussion in the Congress Center – rivaling any about the economy – on what exactly the best 1980s video game was. (OK, I was involved in that one).

It's been a low-key WEF as expected, but it's always impressive when the world's great thinkers get together.

The Turkish prime minister was the unquestioned Davos personality.
