10. Stealing Urine
Speaking of stealing, people have been known to get away with stealing their sample from the tray among many other urine samples. In the case that I heard, the person being tested never got the test results, and was hired for the job that he was tested for. They wouldn't dare ask someone to re-test because they "lost" a urine sample. Don't expect this method to work if you are being tested for the military or if you're on parole. They have no problem violating your rights repeatedly.
