Mum Got Schooled

Here is the conversation whilst driving home from school the other day:

Mum: How was lunch?
Owen: Really good.
Mum: What was for dessert?
Owen: Nothing.
Mum: Nothing? You always have dessert.
Owen: Mum, dessert is called pudding and it's not lunch. It's dinner.
Mum: I know that, you know what I mean! What was the pudding?
Owen: Tubby custard.
Mum: For real, tubby custard?
Owen: Yes, for real.
Mum: Like the Teletubbies?
Owen: Yes, and it's pink.
Mum: Does it come ot of a machine like on the Teletubbies?
Owen: No, the dinner ladies give it to us.
Mum: Does it taste pink?
Owen: No, it tastes like regular custard.
Mum: Sounds good. (In my head) Mum, dinner ladies, dinner, pudding and tubby custard... what's next?
