I don't either. Its an old play on words that kids have been using for years. At church camp picnics we used to have a table of "cruci-fixins" for the hotdogs and hamburgers and at dinner on the last night of camp, the cafeteria door had a sign declaring it was the "last supper". There was an episode of the Simpsons that had a "cruci-fixins" table at a church picnic.

Donald Wildmon up in Tupelo is having a stroke about though: http://www.afa.net/
