I give you, Lonely Girl Meets the Church Lady:
Obviously, it's schtick. She has other videos which are better, but this one is the most timely.
Update: It says if you click on the video that LaughAloneTV owns the rights now. Looks like someone gave her a job.
Update 2: Kotaku has a good article on the story so far.
The point is she caused a stir because Christians DO act like that, and it sucks. Let that be a lesson to us.
