What's the WORST word I can call my Mommy and not get in troube?

Me:  Go brush your teeth really good so that wobbly tooth will be clean for the tooth fairy.

Schatz walks back to the back of the house, but returns to the living room too quickly.

Me:  Did you brush your teeth?

Schatz:  I keep TELLING you....I don't want to brush my teeth until this wobbly tooth comes out.

(She has not "been telling me".)

Me: Come on.  We'll go brush teeth together. 

Schatz (dragging her feet):  Why do I have to brush TEETH and brush HAIR and takes BATHS?!?

Me:  Because I want you to smell nice for school.  I don't want you to be the smelly kid.  

Schatz:  You shouldn't say that, Mommy.  You are being so RACIST!
