as a youngster I was an altar boy. Once when I was serving with a kid we called "Munchy" I got him so flustered that he jammed this round bronze plate at the end of a stick into some old ladies throat because he wasn't paying attention and laughing at my antics. We used the plate on a stick to keep the Body of Christ from ever hitting the floor. You just never knew when a person was going to flinch or sneeze or whatever while receiving communion. It was our mission to never let that round piece of rice cake hit the floor. Many years ago, you couldn't put your grubby paws on the communion wafer. You had to stand and put your tongue out and the priest would lay the wafer on your tongue. This is when we sprang into action! We would shadow the priest off of his right shoulder and as he laid the wafer on a tongue we would follow the trajectory from below with the round plate. The plate was about 6 inches in diameter. I remember making Munchy laugh as he was moving the plate forward probably a bit too fast right into the throat of an older woman who was moving forward. She went down on her fanny clutching her throat.
I could also get Munchy to ring the bell at the wrong time during the service which greatly upset the priest. One time I did that he slapped me around a bit after Mass walking home.
Cheers!
