McKEESPORT, Pa. -- Was it a severed penis or a prank?

That's the question police were asking on Thursday night when they were called to the GetGo on Fifth Avenue in McKeesport.

Police got a call about 5:30 p.m. that said a man walked into the GetGo bathroom, cut off his penis and then handed it to the cashier and asked for it to be heated up in the microwave.

The story quickly became the talk of the town.

"'Somebody took a penis to GetGo and asked them to microwave it,'" Loretta Bray, of McKeesport, said. "I said, 'You're out of your mind.'"

But McKeesport Police Chief Joseph Pero told Channel 4 Action News reporter Bob Mayo on Friday that the penis turned out to be a prop filled with urine.

Police said the woman was going to take a work-related drug test and she had a male companion fill the fake penis with his urine, which she planned to pass off as hers.

The woman and the man went to the GetGo to have the fake penis heated in the microwave so that the urine would feel body temperature, police said.

"It had to do with somebody getting a drug test. And there was a fake object that was brought with urine inside, and they were using the microwave to heat it before the drug test was given," said Pero.

Police said the man handed the teenage girl clerk something wrapped in a napkin to heat.

When it gave off a foul odor, the clerk opened it to find what looked like a penis, police said.

That's when police said the couple took it and fled.

Devices used to cheat on drug tests -- like the one in this case -- are sold on the Internet.

The biggest brand -- the Whizzinator -- has been the target of congressional hearings.

Vikings running back Onterrio Smith was detained at an airport when security found one in his luggage.

As for trace evidence left in the restroom, "there was a small amount of blood on some gauze, which also is pertaining to this as far as this person going for a job application, for a blood and urine test," Pero said.
