Exaggerated: The art collector buys an old fast-food wrapper Bob crumpled up and threw away, and he's regarded by all who see it as being on par with Michelangelo.
Downplayed: Bob manages to sell some paintings, but he doesn't consider them to be True Art or even his best work. The art collector he sells them to, and the people who come to the museum, think they're awesome.
Justified: The art collector has a thing for outsider art, and sees artistic potential everywhere.
Inverted: Bob creates a painting or a sculpture, which is not interpreted as True Art, but as garbage.
Subverted: The broken sink is not well-received at the gallery opening.
Double Subverted: But then some wealthy whackos take interest in it.
Parodied: The museum is filled with random junk collected at the junkyard featured as works of art.
Conversed: "I bet Bob is going to try to pass that junk off as art later on"
Deconstructed: At the same time as Bob is selling his "masterpiece", we see an actual starving artist holding a good (but not amazing) painting out for judgment and being completely ignored.
Reconstructed: The starving artist realizes his mistake, trashes his painting and sells it as a modern art masterpiece for millions.
Played For Drama: Bob is married to Alice, a struggling artist. He supports her, but isn't very artistic himself. Then one day, he is seen scrapping a broken sink, and becomes an overnight sensation in the art world. Alice is jealous that Bob gets famous without even trying, and her artwork that she pours her heart and soul into is barely acknowledged as being art.
