A trip to the Doctor

One day my friend told me that his uvula(the little flap of skin
hanging down in front of your throat) was hurting, and he needed
to go see a doctor. Now, he was trying to impress her, and so he
asked me for the scientific name for it. I told him, and off he
went. He came back over to my house a few hours later, with a
face redder than a fire truck. Apparently, when the doctor asked
him what was wrong, he replied that his vulva was sore.
