I have this friend who always seemed to lean slightly to the left all
the time.

It used to bother me, so I suggested he see a doctor, and have his
legs checked out.

For years, he refused... told me I was crazy.

But last week, he finally went, and sure enough, the doctor
discovered his left leg was 1/4" shorter than his right.

A quick bit of orthopedic surgery later, he was cured, and both legs
are exactly the same length now, and he no longer leans.

"So," I said, "You didn't believe me when I told you a doctor could
fix your leg."

He just looked at me and said, ... "I stand corrected."
