Could one of you scholars please explain the joke for us smoothbrains who don't get it? All I see is a boolean matrix, and I'm not even sure that is correct.

A square matrix with the ones in the diagonal is called the identity matrix

It's an identity matrix. You multiple a vector with it and the result is still the same (identical) vector
