Stupidity is contagious. It gets us all from time to time. Even respectable companies can catch it. As I do every week, let's take a look at five dumb financial events this week that may make your head spin.

1. What are words for?
Google (NASDAQ:GOOG) usually doesn't stick its foot in its mouth. It's usually too busy kicking the competition with said foot. However, CEO Eric Schmidt blundered when he called Twitter and its copycats a "poor man's email systems" during a technology conference this week.

Twitter is a media darling these days, but that doesn't mean that Google is authorized to take it down a peg or two. It actually comes off as jealously childish. Remember when Microsoft's (NASDAQ:MSFT) Steve Ballmer called social networking "faddish" two years ago, when Facebook was the media darling? It went on to pay plenty for a small stake in Facebook three weeks later.

Schmidt clarified the comments with CNBC on Wednesday. He also showed Twitter a little nod of approval.

"We admire Twitter," he said. "We think Twitter did a very good job of exposing a whole new way to communicate."

Cool, then hot? Sounds like love to me. I think Schmidt just telegraphed his company's next buyout.

2. You have the right to remain silent (NASDAQ:AMZN) finally caved in to book publishers and authors who were concerned about the "read-to-me" feature that uses text-to-speech conversion software to read e-books aloud when the Kindle owner isn't able to physically read a book.

I think Amazon is a wimp. It's the one that should be calling the shots. It is becoming such a revolutionary force that even Barnes & Noble (NYSE:BKS) is willing to cannibalistically gnaw on itself to have some skin in the e-book game.

It was silly to give in to the ludicrous notion that this would eat into audiobook sales. This isn't a rich reading. It's a creepy phonetically-challenged computer voice! Besides, who would buy a book and an audiobook? And isn't someone going to go through more books with this feature enabled?

The dumb publishers will be the ones that pay the ultimate price here. Amazon is making it optional for individual publishers to turn off the "read-to-me" function on for their own titles. So now publishers who are selling usability-crippled e-books will have to compete with the unshackled ones. I love it. The free markets will smoke out the near-sighted publishers.

3. The new Mickey Mouse club
Somewhere out in Burbank right now, someone is dreaming up a way to print mouse-eared DVD mailers. Disney (NYSE:DIS) CEO Bob Iger turned heads at an investor conference this week, announcing that the family entertainment giant is considering the launch of an online movie subscription service. The offering would allow members to access streams of Disney's growing catalog as well as receive DVD rentals by mail.

Yes, it sounds a lot like Netflix (NASDAQ:NFLX). The key roadblock here is that studio-specific subscriptions are hard sells when companies like Netflix offer more than 100,000 titles from countless studios.

If anyone can make this work, it's Disney. It has a rabid fan base. It has hot properties at the moment. It has the resources to create exclusive content. Unfortunately, I have to lump this one in the "dumb" file, even if Disney could probably make this work in a kinder environment. If studio-agnostic services have failed to gain on Netflix, it's hard to fathom a standalone studio making it fly.

4. Make it a Blockbuster fright
If Blockbuster (NYSE:BBI) ever wants to open its chain of theme parks -- and former helmsman Wayne Huizenga actually did at one point -- it may as well hand roller-coaster developers this week's stock chart for inspiration.

Blockbuster's stock fell by a sharp 77% on Tuesday, before more than doubling on Wednesday.

Why the wild ride? Well, the big hit came when The Wall Street Journal reported that the company has hired a law firm to explore its financing options. Investors bailed on the movie-rental behemoth, fearing another retail bankruptcy. However, the stock bounced back the next day, when the company refuted the reorganization chatter and announced a healthy 4.4% gain in comps for the holiday quarter at its domestic stores.

The moral of the story for Blockbuster: Don't be so opaque. If you hire a law firm that has worked on bankruptcies in the past, go public with your intentions before the public makes assumptions.

5. Beauty is the eye of the beholder
Fortune published its annual list of the world's most admired companies. I guess it's a sign of the times when you have to settle. Not to be cynical, but let's go over the list without giving names:

  • No. 1 is a company that posted lower earnings over the holidays, and its CEO has taken a hopefully temporary leave of absence.
  • No. 2 just posted its biggest loss in its CEO's 44-year history at the firm.
  • No. 3 is an automaker. Yes, it makes cars.

If you need more hints, feel free to check out the list. Admiration, like so many other things these days, is clearly relative.
