When I was a senior in high school in the winter of 1963, I broke my leg on a toboggan accident, and ended up in the hospital for about 4 days waiting for the swelling in my leg to go down before they put the cast on my leg. Back then, it was standard practice for the nurses to check your temperature every 4 hours around the clock, day and night. It also apparently was standard practice to check your tempature rectally, either that, or they just enjoyed putting thermometers in my butt. After it had been done a few times, I asked the nurse what was the matter with my mouth. The nurse looked quisically at me and said: "I don't know, what's the matter with your mouth?" I said nevermind, and just let her put the thermomoter in my butt. Actually, it felt kind of good, but I didn't want to let them know that I was rather enjoying the procedure every 4 hours for the few days I was there.
