Noah's going to work

Here is the story. Noah pulled a stool and put beside the table, to the middle of his room. I was wondering what or why he was doing that, so I asked. And here's his replies.

Noah : I'm going to work. Have to make more money, just like daddy.

And he was sitting there, pretending he's working.

I wonder where he got the idea from, and what made him thinks that's how daddy work.... it's just funny how/ what the kids can do.
