Smarty Pants

I didn't want to brush my teeth last night.  My mom and I were negotiating in the bathroom.  I could tell she's getting tired and that's when she resorted to her scare tactics to get me to brush my teeth.  She said, "I'm going to turn off the lights, leave, and lock the door."  I looked at her then looked at the door knob and said, "Mommy, the lock is inside.  I can just unlock it."  Then she said, "Just brush your teeth, please..."

Duh, mommy.  Duh.
