A Blueberry by Any Other Name...

 One night someone passed gas in the car....

Brat Child: That stinks. It can't be mom it doesn't smell like her farts.
Big E: What do her farts smell like?
Brat Child: Blueberries

Gassy

Says it all, really.

Manners

While having breakfast at McDonald's, The Brat Child let out a massive belch.  I instructed him to say excuse me, and while I was doing that he was purposefully pushing out another one.

Me: You don't let your mouth hang open.  Please keep your mouth closed if you have to belch.
Brat Child: Well, I can't close my butt!

(Because eventually, everything goes back to farting)
