Panel 1: Car hits pedestrian. Driver: "Oh shit!" -- Panel 2: Driver (with first aid kit): "Someone call an ambulance!". Pedestrian (bleeding, lying on the street): "Will somebody please say a prayer?" -- Panel 3: Driver (bandaging pedestrian): "Is anyone here who knows a prayer?". -- Panel 4: Onlooker: "I do.". Driver: "Then speak it!" -- Panel 5: Driver and onlooker close their eyes. Onlooker folds his hands. Onlooker: "Be present at our table, Lord. Be here and everywhere adored! These mercies bless and grand that we ..." -- Panel 6: Driver looks grimly at onlooker. Onlooker: "... may feast in fellowship with thee." Again, I do not know the origin of this joke. If you know it, please let me know.
