How do you spot a liar?

Other lies are easy to pick up. Chocolate on the face of a toddler who says he never touched the chocolate box is a good sign that they've delved into the chocolate!

Body language, and it's all in the eyes. Lack of eye contact, and eyes moving in one direction (I think we learn't in NLP it was to the left, need to double check that), as well as fidgeting and soft tone with a lot of "ums" and "ahs" thrown in.
