A Hat is a type of unskilled laborer and fashionable headgear, usually worn on the fo- Uh I mean head. Not to be confused with a cap or hair, hats are relatively common in comparison to other bodily accessories such as your cock and genetilia. Though a hat can also be cosidered a condom of the head. This "hat" ensures that the head does not accidentally impregnate the sky creating unforseen consequences.
Among dogs, hats are more commonly worn by their fleas. The insulation and padding provided by the hat protects the more delicate brain casings of these fragile creatures. More robust dogs may wear hats for fashion purposes or in certain situations requiring headgear.
