A man goes to the doctor with a swollen leg. After a careful examination, the doctor gives the man a tablet big enough to choke a horse.
“I’ll be right back with some water,” the doctor tells him.
The doctor has been gone a while and the man loses patience. He hobbles out to the drinking fountain, forces the tablet down his throat and guzzles water until he finally gets it swallowed. Then he hobbles back into the examining room. Eventually, the doctor comes back with a bucket of warm water.
“Okay,” he says. “After the tablet dissolves, soak that leg for at least 30 minutes.”
