Football Math

A football coach walked into the locker room before a big game, looked over to his star player and said:

- I'm not supposed to let you play since you failed math, but we really 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, so the coach looked into his eyes intently and asked:

- Okay, now concentrate hard and tell me the answer to this: What is two plus two?

The player thought for a moment and then answered:

- 4?

- Did you say 4?! - the coach exclaimed, excited that he had given the right answer.

Suddenly, all the other players on the team began screaming:

- Come on coach, give him another chance!
