Robert to Doctor: “Doctor, I have a serious problem. I dream of football matches every night."

Doctor: "Don’t worry. I will cure it right now. Take this pill and you will be alright.”

Robert: "Doctor, would it be okay to wait and take the pill tomorrow?”

Doctor: “Why?”

Robert: “Doc, today is the final match. I have to see the season through and know which team is going to win it all!”
