Paris' finger smells REALLY bad if she's told a lie. Strangely though she won't let me smell it sometimes...

I remember reading the funniest story one day. A little kid was in a line at a bank with his mum, and he was chucking a major wobbly. He looked up and saw the security camera and stood very still. He then turned to his mother and said "Mummy is that how Santa watches us?" She took it and ran with it. And after that no matter where they were all she needed to do was point out the camera and he was as good as gold.
