Art history parodies

I recognize most of the works of art except one, the declaration of independence. From the artworks i did recognize i found to be funny because of how Lt. Pike is being viewed in the parodies. I realize that these parodies were artworks discussed in class. Each parody differentiate from each other but some of them have a common factor which is that they show a fight for freedom. Now that i have studied these artworks i can relate to the parodies because i know what the artwork represent.
