Generally speaking, the guy bugs me to no end. Total blowhard. But I agree with the above poster — any fan of the Billy West days should check out the recent interview he did with Billy on his podcast.
The Nose Touch - In essence, the nose touch gesture is a sophisticated, disguised version of the mouth guard gesture. It may consist of several light rubs below the nose or it may be one quick, almost imperceptible touch. Like the mouth guard gesture, it can be used both by the speaker to disguise his own deceit and by the listener who doubts the speaker�s words.
The Eye Rub - 'See no evil' says the wise monkey, and this gesture is the brain's attempt to block out the deceit, doubt or lie that it sees or to avoid having to look at the face of the person to whom he is telling the lie. Men usually rub their eyes vigorously and if the lie is a big one they will often look away, normally towards the floor. Women use a small, gentle rubbing motion just below the eye, either because they have been brought up to avoid making robust gestures, or to avoid smudging make-up. They also avoid a listener�s gaze by looking at the ceiling.
