A woman rushed to see her doctor, looking very worried and all strung out.
She rattled off, "Doctor, take a look at me. When I woke up this morning, I looked at myself in the mirror and saw my hair all wiry and frazzled up, my skin was all wrinkled and pasty, my eyes were bloodshot and bugging out, and I had this corpse-like look on my face! What's wrong with me, Doctor?"
The doctor looked her over for a couple of minutes, then calmly said,
"Well, I can tell you one thing . . . there ain't nothing wrong with your eyesight."
