Time For The Cheaters To Tap Out

Many years ago, my grandfather taught carpentry at a tech college, and part of his job involved proctoring written exams.

During one of these exams, a couple of students were tapping their pens. On the face of it, this wasn’t so unusual; plenty of people in exams tap pens, drum fingers, etc., as an aid to memory — or at least, they certainly did when I took my exams. These taps, however, seemed rather more… rhythmic.

A few taps later, Grandfather — who was in the naval cadets as a boy — realized that these two students were using their pens to tap out the answers to various questions in Morse code. 

Without saying a word, Grandfather picked up a pen of his own, glaring pointedly at the guilty students, and tapped out the phrase, “I K-N-O-W M-O-R-S-E C-O-D-E T-O-O.”

Funnily enough, the tapping stopped immediately after that!
