Some years back, after several exploratory operation involving general anaesthetics I was told I needed 'It ALL Taken Away' ... womb, ovaries, cervix, because of 'pre-pre cancerous signs'. Not happy, but consultants know best ... Was booked into a very posh London hospital, 'cos I had medical insurance (those were the days ...) Very nice lady gynaecologist who was doing the surgery, also rather stern lady anaesthetist visited me prior to op. On day of the surgery, I was dreading the whole thing, of course, but thought I'd lighten things up. My right hip was buggered, and I knew I'd sooner or later need a hip replacement. So just for a laugh, I stuck a little yellow 'Post It' note onto my right hip, just below my 'lady bits', saying 'Dear Operating Theatre, while you're at it, would you do a quick hip replacement at the same time?'
Next day, through a haze of morphine, I appreciated the gynaecologist's visit, when she said my note made her and the theatre staff laugh. But the lady anaesthetist also visited, fiddled with my morphine pump, and told me through gritted teeth that my Post It note was NOT funny and all it showed was that I had 'a very flippant attitude'.
I still think it was funny, and no, before you jump to conclusions, the morphine pump still worked fine.
