A snorkeler out on the Colorado River was stunned to find what appeared to be two skeletons having a tea party on the riverbed on Monday, alerting authorities to what they thought were human remains.

La Paz County Sheriff deputies and the Bucksin Fire Department responded to the call, dispatching a diver with a video camera to investigate.

"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.

This wasn't a case of a very peculiar burial or tea party gone wrong however – and the aviator sunglasses and bib one of the skeletons was wearing was a dead giveaway.
