This unifies different aspects of humor like:
- Someone disappearing from a child's field of view and then reappearing again (peekaboo) when the child doesn't expect things to exist if they're not perceived.
- A clown whose behavior is unusual.
- A complicated political joke in a stand up comedy act, that establishes a background and provides some twist in a punchline.
- Even something as simple as a photo. The sight of Santa Claus riding an Arley Davidson might be funny. Whether you start by recognizing Santa or the bike, the next thing you recognize is totally unexpected, even contradictory, it doesn't fit.
How does laughter fit in then? In this context, laughter seems to have the role of broadcasting our recognition of something funny to other persons.
Ironically, this seems surprisingly simple and banal for a description of something apparently so special and complex, but as anyone might ask at this point... Why did such an odd thing ever came into being? What's the reason and purpose behind the development of humor? Where does it fit in the framework of man's biological evolution? Why would natural selection favor men with a sense of humor?
