Grand Theft Auto 4 Easter Egg - The Church of Scientology

I was dinking around the endless slum that is Alderney and I noticed the church in Leftwood had a vague image in the rear-stained class window. When I backed up I saw a volcano and knew immediately it was a reference to the L. Ron Hubbard kook-fest that was "Dianetics".

Hoping to confirm this I walked around to the front and saw a man ranting. I got close enough to hear him say two phrases - the only two I needed.

"Biology doesn't exist!" and "You're nothing but a probability wave - IN SPACE!" which is of course a very funny mockery of Hubbard's ridiculous attempts to sound scientific = pseudoscience.
