Just Too Smart?! (2)

A patient limped into his doctor's office complaining about his sore foot. The doctor handed him a large pill. Just then, the nurse called the doctor out of the room to ask him a question. While the doctor was gone, the patient hobbled over to the sink, ran some water in a paper cup and swallowed the pill. Just then the doctor returned with a bucket and said, "Now, drop the pill into the bucket and we'll soak your foot."
