"He said neither he nor TJ did anything to influence museum visitors, such as standing around and looking at the glasses. Within about three minutes, people appeared to be viewing their handiwork as bona fide art, though Kevin said that without his glasses, he could not see what was happening too well."
I say an art prank is art anyway, so what difference does it make?*
It's nice that some teenagers thought of doing this and pulled it off so quickly and elegantly, but we've seen things like this many times before, perhaps more commonly in the form of someone in a gallery staring at something that's not an artwork and causing others to regard the thing as art. I seem to remember reading about Salvador Dali doing something like that. And of course there are all the stories about some artwork being seen as trash and thrown out.
*The difference is, you're putting your art in someone else's gallery, without invitation. It's like hanging one of your own paintings on a museum wall. Or... that would damage the wall. It's like making a drawing on a Post-It note and sticking it up next to drawings in a museum.
ADDED: Back in 2011, Meade put his whole-body art in the Milwaukee Art Museum right next to the Duane Hanson sculpture, "Janitor":
