A pair of sunglass-clad skeletons were caught lounging in lawnchairs beneath the Colorado River on Monday.
Divers discovered the duo 40 feet beneath the river near the Arizona-California border on Monday morning, after a snorkeler spotted the bones and reported them to police, thinking they were real.
"When firefighter Foerstner located the alleged remains, he found it to be an underwater tea party with two fake skeletons sitting in lawn chairs," the sheriff's department said in a statement.
Divers plan to recover the skeletons later this week, and some officials are considering placing them outside the sheriff's office as a joke, according to the sherriff's office.
Officials say they don't plan to locate the person responsible for the skeletons.
