Surreal humour is a form of humour predicated on deliberate violations of causal reasoning, thus producing events and behaviors that are obviously illogical. Portrayals of surreal humour tend to involve bizarre juxtapositions, incongruity, non-sequiturs, irrational or absurd situations, and expressions of nonsense.

Humour or humor is the tendency of experiences to provoke laughter and provide amusement. The term derives from the humoral medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as humours, controlled human health and emotion.
Humour can be a way of dealing with the menacing or unpleasant: Sprayed comment below a memorial plaque for Alois Alzheimer who first described the memory-damaging Alzheimer's disease – the German text means "Alois, we will never forget you!"
