It’s Friday, so let’s have a look at what’s happening in the ‘sphere.

Danny Choo has been spotted in his Storm Trooper outfit before, jamming out Guitar Hero style in Japan or infiltrating the iPhone 3G lines last Friday. Unfortunately, sometimes his intentions are a little darker than that. For one of his most recent romps, Danny decided to Rick Roll the entire city of Tokyo. And I thought getting Rick Rolled online was bad.

Kacper Wrzesniewski once suffered from what some may call George Constanza syndrome: his wallet was too fat. In an effort to be a little more efficient (and straighten out his back), Kacper finally decided to unclutter his wallet. What can you do without? What absolutely has to be in your wallet?

Damien Riley noticed that American workers could be working too hard, because they’re not taking enough vacation days. You may think that you are being more productive by working more, but you could actually be hurting your efficiency. With that in mind, it’s important that you take one for the team and go on vacation. Your family and your employer will thank you.

Mr. List, as you can probably tell from his name, has a thing about making lists. As Twitter and other similar services rise in popularity, Mr. List has determined that microblogging is dumbing us down.

Kirai Net came across a very interesting method for building demolition. When they get rid of a hotel resort in Las Vegas, they just implode the entire thing in a whole lot of well-placed explosives. Such is not the case in Japan, as evidenced by this video. Instead of blowing up the whole thing, they tear the building down one floor at a time, starting from the bottom.
