It was Friday morning, and that meant it was time for an activity that the teacher called 'Add to the picture' .
The teacher would call students to the chalkboard one at a time. The first student would draw an object on the chalkboard, and each following student would add something to the picture to make it a new picture.
The teacher called on James to start things off.
James returned to his seat.
The teacher called on Ernie next.
Ernie returned to his seat.
Now it was Suzy's turn.
Suzy returned to her seat.
Next, the teacher called Jerry to the board.
Jerry returned to his seat.
Kim was called to the board.
Kim returned to her seat.
About this time, little Johnny began waving his arm hysterically. Little Johnny was well known for being off centre, so the teacher was reluctant to call on him for anything. But as the teacher looked at the picture on the chalkboard, she thought that there was no way that little Johnny could possibly do anything to make this picture dirty. So she called on little Johnny, and he ran to the chalkboard.
The entire class erupted with laughter.
