A local goat farmer was selling smart pills. Small round natural looking pills that he guaranteed were natural and organic. I bought some and tried them and the next time I saw him he asked me what I thought of his “smart pills”. I said I guess they were okay but they tasted like sh*t. He said “See, you’re already getting smarter”.
