Office Worker: Do you know if this kid’s grade is right?
IT Guy: How would I know his grade?  I am not his teacher

Office Worker: Just tell me his grade
IT Guy: How the hell would I know his grade? 

Office Worker: Well you do the grades don’t you.
IT Guy: Yes, I do.  What I don’t do is memorize the 6,300 grades that pass through my computer.  I understand you are very impressed with my ability to sort things in Excel but that does not make me the freaking Rain Man

Office Worker: So how do I find his grade if you don’t know it?
IT Guy: ASK HIS TEACHER!!!!!!!!!!

Office Worker: Fine, I’ll try it.
