My ride home yesterday

What's that black stuff?  (asphalt to fill a pothole.)
What's a pothole?  (a hole in the road.)
Will they have to spray something on it?  (no.  the cars driving over it should smash it down.)
Why are there holes in the road?  (roads just wear out after lots of cars drive on them.)
Will your tire pop?  (old, worn out tires might.)
Are our tires old?  (no.)
Do you have new tires?  (yes.)
Do tires last forever?  (no.)
Do wheels last forever?  (yes. :-/ )
What's that grey thing on wheels?  (hubcaps.)
What's a hubcap do?  (don't know.  it might help hold the tire on.  you'll have to ask daddy.)
What came first, roads or cars?  (cars.  they built roads like this for cars to drive on.  before it was trails for horses and buggies.)
What's a buggy?  (like a stagecoach.  like at the bank building.)
Are those cactuses real?  (yes.)
Is that stagecoach real?  (it's a replica.) 
What's a replica?  (something new that someone built to look like something old.)
What's that?  (scuba diving sticker.)
Why's it on their car?  (guess they want people to know they're a scuba diver.)
What's scuba diving?  (swimming with an air tank so you can breathe through a hose hooked to it and not have to come up for air for a long time.)
Are there fish in that pond?  (don't know.)
Well there are ducks in that pond.  (yes.  there are.)
There's Nanny's car.  (yep.)
Where's Pop's car?  (not here.)
Is Lulu awake?  (don't know.  go find out.)

I felt like I was on a game show.  I was really nervous that at any point he might yell, "You are the weakest link!"  It was exhausting.
