A man calling himself "Louis Slungpue" and claiming to be a DWP spokesman called up the station and actually got on the air.
After informing reporters that the pronunciation of his name was "slung-poo," the prankster speculated that flushing a cherry bomb down the toilet could have caused the problem.
"We're in the investigation phase. Either a cherry bomb or someone took a really large dump," Slungpue said.
His silly statement was met with, "That is incredible. Are you 100 percent sure about that?"
Someone at the station eventually figured out it was a prank and Slungpue was cut off.
