A man went to the doctor with a swollen foot. After careful examination, the doctor gave him a huge pill. “I’ll be right back with some water,” the doctor said. The doctor was gone quite a while and eventually the man lost his patience. He hobbled to the sink, forced the huge pill down, slurped water from the sink until the pill cleared his throat, and then hobbled back onto the examining table. In walks the doctor with a bucket of warm water. “Okay, once the tablet has dissolved, soak your foot in it for at least a half hour.”
