California style Being nervous and embarrassed about my up-coming colonoscopy, on a recommendation, I decided to have it done while visiting friends in San Francisco, where the beautiful nurses are allegedly more gentle. 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 don't have an erection," I replied. "I do." replied the nurse. Never get a colonoscopy in San Francisco.
