Salma Hayek sure can tell a story. The one she tells here is hilarious and very much worth the watch. The skilled actress also demonstrates many body language tells - one of which is delineated below.
Notice Ms. Hayek is sitting on her left leg with her left foot all the way up on the coach. This is a signal of significant emotional comfort. Despite her being on The Graham Norton Show with a such a dynamic host and other guests - she is very much at ease during this story.
This is yet another example of the nonverbal communication axiom, that in order for a configuration of the body to be PHYSICALLY comfortable - it must FIRST be EMOTIONALLY comfortable.
Another valuable take-home point here is suppose, that if upon being asked a question or a subject being raised, a person moved out of this comfortable leg configuration and placed both feet flat on the floor - you would know that the issue being raised or question being asked had struck a nerve of anxiety. In such a scenario, this leg position change would often be accompanied by a subtle fear expression on the face (e.g., slightly wider eyelid opening, an inward lip roll, etc.) and/or one hand scratching or holding the opposite arm or back of the head.
