A kindergarten teacher handed out a colouring page to her class:

On it was a picture of a duck holding an umbrella.

The teacher told her class to colour the duck in yellow and the umbrella green,

however, Little Johnny, the class rebel, coloured the duck in a bright fire truck red.

After seeing this, the teacher asked him:

“Johnny, how many times have you seen a red duck?”

Little Johnny replied.

“The same number of times I’ve seen a duck holding an umbrella.”
