A high school student tries out for the football team. The coach says to the student, "Son, I'd love to have you on the team, but it seems you've failed math. So, I'll have to ask you a math question and if you get it right, you can be on the team.
The coach asks, "What's two plus two?"
The student thinks for awhile before saying, "Four."
The rest of the team yells, "Come on, coach, give him another chance!"
