Bridging the consciousness gap

I wondered what makes something funny for a few minutes. Aristotle(or some old dude) said humor Is unexpected. Some recent research said humor is benign.

Of course there are flaws like why do we laugh even if we already know the joke. Why does it take longer for us to laugh at a very creative, witty and unexpected joke? If funny means nobody actually gets hurt, why do people enjoy watching FAIL videos even if they know people get hurt a lot?

I came up with a possible one. Aristotle(or some old dude) is partially correct. Humor is unexpected, but only when our subconscious understands it. Even if we consciously know the joke, our subconscious doesn't and that makes a big difference.

So humor is unexpected and applies when our subconscious actually gets it.

Same applies to habits. You need your subconscious to understand in order for you to actually make it a habit. Repeating a task continuously let's it sink in into our subconscious
