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, according with Dr. Strugatz.
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.
She persuades Peterman to let her take the test again, but a half-hour before the test she realizes that a piece of chicken she ate at Jerry's apartment had poppy seeds on it. She asks Helen Seinfeld for her urine sample and passes it off as her own. It tests negative for drugs, but shows she has the metabolism of an elderly woman; Elaine thus gets her job back but still cannot go to Kenya.
