We are surely shaped by our experience for instance if you never see, hear and see others doing and it determines how we are going to classify and group things in our society. Creating an atmosphere that suit the taste of the audience by painting mental picture of an object, abstract or things in our piece, I believe the response of people towards it will be WOW. Captivating.
Yes, our humour is shaped by own experience and how we look upon the world in general.
But we also have to understand the sense of humour of the world out there, to understand how people relate to things we post. And how instantly it will impact on their minds.
