Hah! Pleasant read. I especially liked this snippet, in which he suggested that you could become a 'cat' when the person you are conversing with is trying to make you a 'dog' (cats being assertive, dogs being passive):

  Them: "Have a seat."
  You: "Let's sit down."
  Them: "Ok."

I upmodded this, but

> teaching a creative or assertive skill (for example, programming or feminism)

feminism is an ideology (preach), not a skill (teach).

Dog: make me a sandwich

Cat: what? make it yourself.

Dog: sudo make me a sandwich

Cat: ok.

I think you got that the wrong way around. The cat is the one who proposes an action.

Yeah, but then it turns into:

Cat: Go make me a sandwich. Dog: Yeah! A sandwich! Yeaaah! Yeah! Oh boy, a sandwich! Yeaaaaaaah!

Nope, according to the article, the dog is quite happy to turn options down.

Cat: Hmm, let's eat something tonight.

Dog: Sure.

Cat: Why don't you cook something?

Dog: Nah.

Cat: Hmm... how about if we just eat sandwiches?

Dog: Sure.

Cat: Well, you gonna make a sandwich or what?

Dog: Nah.

Cat: Sudo make me a sandwich.

...

This arrangement properly demonstrates the power of sudo. :)

interesting idea but the best evidence the guy has is based on Buffy the Vampire Slayer. Anybody have any real world statistics on this?

Start paying attention and you will notice it all around you. Of course it is too simple to explain everything, but still pretty useful method.

What's your problem with Buffy the Vampire Slayer? It's totally scientific as far as I am concerned.
