Tag You're It

Fiona (using her most frantic tattle-tale voice): Daniel scribbled all over the bath tub with a marker! It was him, I know it! Because I didn't do it and he is the naughtiest person in the house!
Me: Daniel, did you color on the bathtub with a marker?
Daniel: No!
Fiona: You did so! You did!  You're a LIAR!
Daniel: No, YOU'RE a liar!
Fiona: No I'm not! You're a liar! Because I didn't do it!
Daniel: No, YOU'RE a liar!  I'm not a liar!
