Dedicated to Piotr and Jarek who will both be celebrating their first Father's day today.
(Congratulations to Anna and Jarek on your new arrival!)
So, what is a chip off the old block?
A chip, in this sense is not the kind you eat but a small piece of wood. The block is not the kind you live in but a larger piece of wood.
Therefore, we use this to describe someone who is just like his father.
He's a chip off the old block. We can also say, 'like father like son.'
Here's the perfect song for the occasion. Some retro snyth pop from 1972 featuring a Moog synthesiser. As a bonus, it's a kareoke version, so you get to see the words and you can sing along.
