A soccer coach walked into the locker room before a game, looked over to his star player and said: "I'm not supposed to let you play since you failed math, but we need you in there. So, what I have to do is ask you a math question, and if you get it right, you can play." The player agreed, and the coach looked into his eyes intently and asks: "Okay, now concentrate hard and tell me the answer to this. What is two plus two?" The player thought for a moment and then he answered: "I think... no... yes... I’m not sure... what about 4?" "Did you say 4?" the smiled coach exclaimed, excited that he got it right. At that, all the other players on the team began screaming: "Come on coach, give him another chance!"
