Dinner Giggles or, How I Spit Milk All Over Creation

Oh, Crap.
She's at it again.
Whenever we get around each other at mealtime, Carly makes me laugh so hard that I spit out any liquid I'm holding. She waits until I've got the glass to my mouth and then says something like this:

Carly: Did you just say boughten?

Dad: No. I said, bought in.

(huge pause)

Carly: I never know whether it’s bought or boughten, so I just say 'purchased.'
