The federal government is looking for doctors to help monitor suspected smugglers’ bowel movements at John F. Kennedy International Airport in New York, in a solicitation that sounds like it could be something out of the Discovery Channel’s “Dirty Jobs” program.

Doctors must be available round-the-clock in case CBP officers suspect they have a “swallower,” which is what internal drug smugglers are known as. The doctors are charged with X-raying or otherwise examining suspects’ body cavities, and if drugs are found, the work order says “the detainee may be held for a monitored bowel movement (MBM) to wait the passage of the contraband material.”

“CBP regularly intercepts individuals who ingest wrapped packets of illicit drugs such as cocaine, heroin, amphetamines, ecstasy, marijuana or hashish to transport them,” the agency said. “CBP officers apply their keen knowledge, expertise and intelligence to detect and intercept suspected body cavity concealers at our nation’s ports of entry.”

CBP identified 176 “body cavity concealment incidents” in 2014, which was down from 187 the previous year.
