Religious symbol Puns

I have a course in religious symbols at university, and we had an assignment to go around town and take pictures of random religious symbols we would stumble over. Next lecture the Professor had made a collection of the best pictures into a powerpoint and we were to spend two hours analyzing them.
After about an hour we came to this picture of a wiccan pentagram in the window above a animalshelter, and the professor asked: "Why do you think this is here?" before I even had time to think, and stop my self I bursted: Maybe a dyslectic thought it was a PETAgram?
Alot of bored students life got a tad more depressing after that...
