The teacher asks his students to spell the word “before”.
The first kid tries: “B-E-F-O-H-R.” “No”, says the teacher, “that’s wrong!”
Another kid: “B-E-E-F-O-R.” “No, no,” says the teacher. “Anyjoke else?”
A little boy raises his hand: “B-E-F-O-R-E!” “Now, that’s right!” beams the teacher.
“Now, Washington, use this word ‘before’ in a sentence!” and the boy goes: “Two plus two BE FOUR!”
