This is a piece of advice we never thought we would have to give.  In addition to the many other things you must consider during an encounter with the police, now you must consider the tension of your butt.  Earlier this year in New Mexico, a man was pulled over for allegedly failing to make a complete stop at a stop sign.  After the officer asked the man to step out of his car, the officer determined that the man was “clenching his buttocks” and therefore must be hiding drugs in his butt.  The officer obtained a warrant and took the man to a hospital where he was subjected to two rounds of x-rays, two internal anal exams, three enemas and a colonoscopy.  No drugs were found and the man is suing the police.  At no point did the man consent to a search, AND the hospital subsequently billed him for its “services.”  Read the gruesome details here and here.
