So this elderly man came into the Emergency Department with a bloated abdomen. To cut a long story short, vis-a-vis the diagnostic process involving the necessity of analysing a sample of the fluid within his abdomen, my registrar walked into the cubicle a bit later on to find me in the process of cracking open a big barrel of wine, only to find it had gone sour.
"What are you doing?" shrieked my registrar, "I asked you do do an ascitic tap!"
"Oh!" said I, "I thought you said an acetic tap."
