Umbrella in the context of "Rational"

Rationality is the quality of being guided by or based on reason. In this regard, a person acts rationally if they have a good reason for what they do, or a belief is rational if it is based on strong evidence. This quality can apply to an ability, as in a rational animal, to a psychological process, like reasoning, to mental states, such as beliefs and intentions, or to persons who possess these other forms of rationality. A thing that lacks rationality is either arational, if it is outside the domain of rational evaluation, or irrational, if it belongs to this domain but does not fulfill its standards.

There are many discussions about the essential features shared by all forms, or accounts, of rationality. According to reason-responsiveness accounts, to be rational is to be responsive to reasons. For example, dark clouds are a reason for taking an umbrella, which is why it is rational for an agent to do so in response. An important rival to this approach are coherence-based accounts, which define rationality as internal coherence among the agent's mental states. Many rules of coherence have been suggested in this regard, for example, that one should not hold contradictory beliefs or that one should intend to do something if one believes that one should do it.

The Penguin (Oswald Chesterfield Cobblepot) is a fictional character appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. The character made his first appearance in Detective Comics #58 (December 1941) and was created by Bob Kane and Bill Finger. The Penguin is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery. The Penguin has repeatedly been named one of the best Batman villains and one of the greatest villains in comics. The Penguin was ranked #51 in IGN's list of the Top 100 Comic Book Villains of All Time.

The Penguin is a Gotham City mobster who fancies himself the number one "Gentleman of Crime". He is most often seen as a short, fat man with a long nose who wears a monocle, top hat, and morning suit while carrying his signature umbrella. He also has a cigarette holder in his mouth. The Penguin uses high-tech umbrellas as different tools. His umbrellas have been used as guns, gas sprayers, swords/knives, a mini-helicopter and many other unconventional tools. The Penguin owns and runs a nightclub called the Iceberg Lounge which provides a cover for his criminal activity.

Stick-fighting, stickfighting, or stick fighting, is a variety of martial arts which use blunt, hand-held "sticks" for fighting, most typically a simple, non-lethal, wooden staff or baton. Schools of stick-fighting exist for a variety of weapons, including gun staffs, bō, jō, bastons,Naboot, and arnis sticks, among others. Cane-fighting is the use of walking sticks as improvised weapons. Some techniques can also be used with a sturdy umbrella or even with a sword or dagger still in its scabbard.

Thicker and/or heavier blunt weapons such as clubs or the mace are outside the scope of stick-fighting (since they cannot be wielded with the necessary precision, relying on the sheer force of impact for stopping power instead), as are more distinctly-shaped weapons such as the taiaha used by the Māori people of New Zealand, and the macuahuitl used by the Aztec people of Mesoamerica in warfare.
