Pimping the Ride

Now that he knows how to drive and he has his own car; our son is thinking of getting his ride pimped. He and his dad are scheming to power up the car. I'm hearing air boosters and things about turbos. They think I didn't understand that? Hmm, that's where they are wrong. My ears get sharper when I hear expenses coming. I think I'm gonna play hard-to-get.
