What are they showing these kids at nursery?

As I arrived home one evening this week...

Alex: (Running grinning down the stairs with a piece of plastic tube in his hands.) Dad! Dad! This is my boomstick!

Me: Your boomstick?

Alex: (Brandishing the plastic tube proudly) Yeah!

Me: Your boomstick. Um.....

Abi: (Calling through from the living room) It's his broomstick. He's Harry Potter.

Me: Ohhhkay.

(For the uninitiated, here is the full quote from Army Of Darkness: "Now listen up, you primitive screwheads. See this? This... is my boomstick! The 12-gauge double-barreled Remington. S-Mart's top of the line. You can find this in the sporting goods department. That's right, this sweet baby was made in Grand Rapids, Michigan. Retails for about $109.95. It's got a walnut stock, cobalt blue steel, and a hair trigger. That's right. Shop smart. Shop S-Mart. You got that?")
