During the break between morning classes:
Me: Ow, my neck hurts. Must have slept funny.
Friend 1: Do you have mono?
Friend 2: Rheumatic fever?
Friend 3: Tetanus?
Me: Thanks, guys. I appreciate your evident pleasure in my imminent demise.
(Also, I just have to say, that picture of a cross-bred horzebra is possibly the most disturbing thing I have seen in a while. And I am in medical school.)
