Striking The Right Note

(Our chemistry teacher is very smart, but sometimes also strict and a stickler for details. One of my friends is very good at the class, but not quite so detail oriented, and the teacher often gets on him for small omissions. By midway through the year, my friend is getting sick of it.)

Teacher: “[Friend]! Look at this lab report!”

Friend: “What about it? It’s right isn’t it?”

Teacher: “Yes, but you didn’t label the notes and calculations columns! How am I supposed to know which is which?”

Friend: *in a deadpan* “See the column with all of the numbers in it? Those are the calculations.”

(By some miracle, my friend got away with that.)
