Following Directions

After choir tonight in the car Noah kept saying "A PEACH!" I kept asking what he was talking about and he said Mr. Bob says "A PEACH" and all of the kids agree and loudly say "A PEACH." I asked when they said this and asked if it was part of a game.  He said that it is a response after Mr. Bob gives instructions... I asked if he misunderstood and it was actually "Kapeesh?" He said, maybe mom, but that doesn't make sense.....
