One morning, a father and his young son were in the forest hunting rabbits. After about an hour, they finally came across some rabbit tracks. In between the tracks, there were these little round brown pellets, and the son said to his father, "Dad, what are those?"
The father replied, "Those are smart pills. Try a couple." So the kid grabbed a couple of them and put them in his mouth. The boy made a funny face and said to his dad, "Ewww! Yuk! They taste like s---."
The father replied, "See, you're getting smarter already."
