Archie: Pipsqueak! Hear those chimes? That means it’s the ice cream van!
Dexter: What’s ice cream?
Archie: Something we have once a year at the beach or if the ice cream man comes round. It’s the yummiest thing ever. We’re not allowed it very often because it’s bad for your teeth. We get a baby-sized cone – well, I will. Yours might be a bit smaller. You don’t want to get brain-freeze, not when you have a Very Little Brain…
(two minutes later)
Archie and Dexter: Yummmmmmm…
(And, because film really shows it better…)
