HA! I love it. I went to a Catholic high school and one of the teachers was a nun with one of those Sally Field Flying Nun starched headdresses, except that it had a large cavity on top, something like a ship's smokestack, instead of wings. We used to shoot spitballs into the top of her headdress, and we got quite good at it. Apparently she would carefully take it off every night without tipping it. After a few weeks she bent over one day in class to pick up a piece of chalk and the whole pile of spitballs rolled out. We got a visit from the principal. It was less dangerous than your needle but probably more sacrilegious. In my Catholic grade school we were served hot lunches every day, often with a vegetable medley of boiled peas, corn, and small cubes of carrots - you know the mixture I am describing. We would use our forks as catapults to launch the veggies vertically and score points by how many we got to stick into the small holes in the ceiling tiles. After months, the principal looked up one day and saw an entire mosaic of veggies on the ceiling. It was abeautiful Van Gogh Starry Night galaxy of veggies. We had to stand on the table after school for days meticulously picking them out. This was not a sin of sacrilege but, according to the sermon/lecture we got while cleaning the ceiling, one of wasting food. The parhs to Hell are many and various.
