PITTSBURGH - A woman who claimed she was trying to cheat on a drug test was behind a bizarre incident in which a frightened convenience store clerk thought she had microwaved a severed penis, police said... The incident unfolded... when a man and a woman entered the store and the man asked the clerk, "Can you microwave something for me? It's a life-or-death situation,"... The man asked for paper towels, wrapped an object in them, and had the clerk microwave the item for 20 seconds... When it was finished, the clerk handed the item back to the man and saw what she thought was a severed penis... The woman told police she was applying for a job and was required to take a drug test. She said the man had filled the device with his urine, which she planned to submit for the test... the couple stopped to warm the device in the microwave so the urine would "pass the body temperature test,"... police weren't sure why the woman was storing the urine in a device mimicking male genitalia... Giant Eagle, which owns the convenience store, said the microwave will be discarded.
