It was a bit awkward at first, but I explained that the new Jeep Thing is really your second cousin.

Me: Rover, this is your new sibling, the Jeep Thing.

Rover: Where's it from? Does it have 4WD?

Me: It's from America. You know, the country you've been living in for the last 35 years? If you go back to 1948, you have ancestors in common, in fact!

Rover: Well, is it made of aluminum?

Me: Aluminum, steel, and magnesium.

Rover: What's magnesium?

Me: Never mind.

Rover: What's with those ugly bumpers?

Me: They're plastic. Better if you run over a person.

Rover: Oh. Does it have 4 forward gears?

Me: Six. But all of them are a higher ratio than your first four.

Rover: It looks familiar. Do I recognize it from somewhere?

Me: Yes, its grandfather completed the Darien Gap with one of your siblings decades ago.

Rover: Do you still love me best?

Me: Yes, I still love you best.
