For travelers this holiday season, make sure to pack light, keep a sense of humor during an intrusive pat down and, apparently, don't drink too much water.
It's unclear if this is was classified as a terror alert yellow or brown, but authorities took it seriously enough to evacuate the plane.
The U.S. Airways flight was checked by K-9 units when it landed in Denver and the unnamed passenger, reportedly of Middle Eastern descent, was detained momentarily and questioned.
The flight started at Fort Lauderdale-Hollywood International Airport, stopped in Charlotte and then continued to Denver. It's unclear if the passenger was on at the beginning of the flight or got on later.
Nothing suspicious was found on board or in the bathroom. Officials also didn't say how many times the passenger went to the bathroom.
"Per standard procedures, law enforcement and TSA personnel met the flight. The passenger was questioned and released and the plane was swept, both with negative findings," TSA spokesperson Carrie Harmon said in a statement.
Passengers told authorities the passenger was "acting weird" and that set off the terrorist alert in their minds. A check of airplane protocol doesn't appear to suggest that diarrhea or excessive urination are signs of terrorist activity, but better safe than sorry.
The person was not arrested and authorities apparently flushed the concerns.
OK, no more toilet humor. Happy traveling.
