Elaine takes a urine test in order to go on a work trip to Kenya with her boss, J. Peterman. She tests positive for opium. Elaine insists she has never taken drugs, but when a frantic Kramer shows up at her office begging her to let him use her normal-pressure shower, Peterman mistakes him for a drug addict and fires Elaine. Elaine realizes that the test is picking up the poppy seeds in her favorite muffins.
