A Pennsylvania man reportedly pleaded guilty to mailing a bomb to a Chicago doctor whom he paid $8,000 to enlarge his penis.

Brett R. Steidler, a 25-year-old factory worker from Reamstown, PA. was eager to find a cosmetic surgeon who could enlarge his penis.  Steidler located one in Chicago, and traveled there for the costly procedure.

To be frank, there were complications. Steidler was "extremely unhappy with the results," Assistant U.S. Attorney Jennifer Arbittier Williams said in a court filing, according to Philly News.

"It's a very sad case for a young kid from Lancaster County who's had a tough go of it," said his attorney, Luis A. Ortiz.

Steidler is mentally ill, probably bipolar, Ortiz confessed.  Unhappy with his surgery, he simply went berzerk, then attempted to correct a very bad decision, Ortiz said.

For months after the surgery, Steidler repeatedly called the Chicago clinic to complain.  In November 2004, he allegedly sent the doctor a poem "The Surgeon's Hands" and threatened to cut them off.

"To kill him is not enough, for he is already old," he wrote.

In February 2005, from his home in Reamstown, he built a bomb out of black gunpowder, a carbon dioxide cartridge, a nine-volt battery, a model-rocket igniter, and dental floss.

Under the relevant federal statute - 18 U.S.C. Section 2332a(a)(2) - this device now qualified as a "weapon of mass destruction" for which the maximum penalty is life in prison.

Steidler reportedly hid the bomb in a small gold jewelry box and placed the box in an envelope.  He wrote the surgeon's address on the outside and listed the return address as "United Methodist Church in Warren, Ohio," reports Philly News.

Authorities in Youngstown ended up identifying the package as a threat and used a water cannon from a fire truck to disarm it.

Sentencing is set for July 7 before a U.S. District Judge.
