This involves lying on my left side while a gel coated probe is pushed around my chest by the machine operator. Part way through the proc8this morning, there was a knock on the door and another operator said that one of the two other machines wasn't working correctly. Rachel, my echocardiogrammer, asked if they'd tried 'turning it off and back on again'. Naked from the waist up, with my chest smeared with KY jelly, it was hard to suppress a giggle. Maurice, Roy and now Rachel - it's a killer line, everytime.
