A memory

I've told this one plenty of times, but it's one of my favourite "Kids Are Stark Raving Bonkers" tales.

D was going through a phase of fascination with Favourites. Our days were filled with
"Daddy, who is your favourite Star Wars Character?"
"Mama, what is your favourite movie?"
"Daddy, what is your favourite fruit?"
"Daddy, who is your favourite Star Wars Character?" (grumbles: "Same thing as five minutes ago, D")

So anyway, D and I were driving along a major road, going to the shops or something.

D: "Daddy, what's your favourite Insect Orchestra?"
Me: stunned silence
