Because they're all freaks!
James Franco At MoMA
That's not fucking art! That is some douchebag actor trying too hard with some narcissistic weirdo "artist".
"Oh look at me, I can sit in a chair and not speak... I wasn't neglected or abused as a child, I just like this kind of attention for no reason..."
You should sit in a chair and not speak more often James. Behind closed doors, with no cameras, so we will never have to see you again. And please take Abramović with you.
Go fuck yourself MOMA.
