I don't think they are making fun of it I think they are waking up the public.
When Leonardo Da Vinci painted "The Last Supper" he knew of the Vatican's secret of The Bible and its control over the people. He left many codes in his paintings for us to decipher later on. Their religion is all based on Astrotheology. They worshipped the heavens (cosmos). The picture represents the Son of God (Sun) in the middle, 4 seasons & 3 months to each season (spring, summer, fall, winter).
Michelangelo knew this too. They had to hide the truth in their paintings.
