Mathematician 1: I have three sons. Their ages add up to 13. [Looks around] And the product of their ages is equal to the address on that building there.

Mathematician 2: Anything else?

Mathematician 1: My oldest son has red hair.

Mathematician 2: Ah, I know their ages.

What are they?

A husband and a wife of 30 years are being interviewed and are asked how they managed to keep a family together all this time. The wife responds: “It’s all about a clear separation of labor. My husband makes the big decisions and I make the small ones. I choose what’s for dinner, what school our kids attend and what house to get. My husband decides when to declare war on China.”

This really should not have come as a surprise for me, but I was amazed at how different people can interpret the above joke to further advocate their own personal views and opinions. Meh.

The mirror test (Wikipedia article here) is a method of measuring self-awareness by verifying if an animal is able to recognize itself in a mirror. But, really, I don’t see this as anything monumental. It’s not so much testing self-awareness as testing the complexity of the physical model that the organism maintains. (What I am here calling a physical model is the conceptual model of the world we necessarily maintain in our minds. This is the model that allows you to, for instance, walk around your house without concentrating too much on your surroundings, as you know where everything should be and was, the last time your model was “updated”. Unless you have little furry creatures in your house and they are liable to run under your feet.) The mirror test seems to only gauge if the subject’s physical model is robust enough to properly map the external environment to self when faced with contradicting visual input. Nothing more.
