i have seen it before on youtube and some people there have called it a fake as well, anyhow the purpose is to poke ridicule at culture that finds its roots in the religion we all share. even decent non muslims would find it a hideous attempt at humour.
I've seen women asking for screens and lifting-up the veil.. but the one stuffing her mouth over the opening seems extremely fake! People with niqaab's don't let people take pics either..
