Dedicated to Marcin and Sebastian and of course, Daniel
He's just like his father.
You could say, he's a chip off the old block!
In this sense, it's not a chip that you eat but a small piece of wood. The old block is a big piece of wood.
Therefore, he's like a small piece of wood from a larger one.
Here's a song I liked when I was just a small piece of wood. Pretty awful really but I liked it. It was one of the first hit songs to feature the Moog synthizer keyboard.
