The Yellow Duck

A kindergarten teacher handed out a coloring page to her class.
On it was a picture of a duck holding an umbrella. The teacher told her class to color the duck in yellow and the umbrella green, however, Johnny, the class rebel, colored 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?"
Young Johnny replied with, "The same number of times I've seen a duck holding an umbrella."
