(MCT) — LOS ANGELES — The summer swim season is long over, but some of the city lifeguards in El Monte, Calif., fired for spoofing a hugely popular Korean pop video finally got their jobs back — only to resign immediately.

Officials in the city east of Los Angeles fired 13 lifeguards and their manager in September, days after they made a video inspired by the global hit “Gangnam Style.” Because they were wearing city-issue red trunks and the filming occurred at the city aquatics center, it was deemed an inappropriate use of city resources.
