Phlebotomy
When I was last in hospital, some tests needed running on my blood. I wasn't overly excited about this, but when the doctor told me that a phlebotomist would be with me shortly to take my sample, the loveliness of the word did much to distract me from my discomfort.
Of course, at the time I did not reflect on how near in sound are "phlebotomy" and "lobotomy".
