Being laughed at is painful. This is particularly true when it occurs at a very sensitive moment. Compound that with the laugh coming from someone with whom you are open and vulnerable and the hurt is compounded. The most common theory of humor is the theory of incongruity. This would be where the outcome produces a twist from the expected. This might actually be similar to the relief theory. Then there is the superiority theory.
