I am not vouching for the website but apparently they got access to the 92-point checklist the TSA uses to spot a terrorist. Apparently yawning at the checkpoint is one of those things that tip off the SPOTniks that the person might be "hiding" something or could be a terrorist.
Of course TSA had no comment. What a bunch of horse apples.
