A group of Sisters were being thoroughly trained by their Superior to play perfect hosts on the maiden visit of their Archbishop to their convent. Naturally the young ones were quite nervous about the whole procedure. When the Bishop arrived, (luckily he was one of the down-to-earth guys) he sat for meals and then asked the Sisters also to join him rather than everyone running around the table and him. This was not something they were ready for. Anyhow they began their meal ... but in stiff silence! The Bishop tried to make them feel comfortable. One of the young ones trying to break the silence blurted, "Your Gravy, please pass the Grace!"
