Many parents forced to listen to "Baby Shark" have joked it's like torture, but that's exactly what it was used for at an Oklahoma jail.
Court records show inmates in Oklahoma City were chained to walls while the popular children's song played on a loop for up two hours.
Investigators blame two former detention officers and their supervisor.
All three are charged with cruelty.
The song was also used last year in Florida to keep homeless people away.
