When a physician remarked on a new patient's extraordinarily
ruddy complexion, he said, "High blood pressure, Doc. It comes
from my family."

"Your mother's side or your father's?" I asked.
"Neither," he replied. "It's from my wife's family."
"Oh, come now," I said. "How could your wife's family give you
high blood pressure?"

He sighed. "You oughta meet her mother sometime, Doc!"
