Being nervous, and embarrassed about my upcoming colonoscopy on a recommendation I decided to have it done while visiting friends in San Francisco, where the beautiful nurses are allegedly more gentle and accommodating. As I lay naked on my side on the table, the gorgeous nurse began my procedure. "Don't worry, at this stage of the procedure it's quite normal to get an erection," the nurse told me. "I haven't got an erection," I replied. "No, but I have," replied the nurse. Don't get a colonoscopy in San Francisco!
