FBI agents and Russian killers pursue a man and woman, Ralph's students are disillusioned and preparing to drop out of school, and Bill is given a lie detector test where he is caught covering for his extra-terrestrial and super-suit escapades, causing him to be suspended from the FBI until he takes a follow-up test. Bill comes up with a plan to resolve the high-profile FBI case in order to buy himself out of the failed test predicament, enlisting Ralph and Pam to help him. Written by Anonymous
