I was hooking my patient (a 30 something year old male) to an ECG and was explaining the procedure to him as I did so. I had explained to him that this machine measures the electrical conduction within the heart. Once he was all wired up I asked him to lie still for me, and from the patient comes a chuckle and I hear him say in a robot voice… “I….AM….ELECTRO…MAN…!!!” I nearly died of laughter!!
