Explain this type of humor

Explanation: there is a saying that when you run the bath, instead of using the word “run” they say draw. so the little boy things that the grandma is actually drawing the bath with crayons markers etc. so he says he already knows what it looks like and that she doesn’t need to draw it on paper to explain it to him.
