During one flight on Cebu Pacific Airlines, flight attendants took a few extra steps to make sure passengers learned about in-flight safety. With the help of Lady Gaga's "Just Dance" and Katy Perry's "California Gurls," they performed a choreographed version of their typical instructions. A representative from the Philippines-based Cebu Pacific said it was simply a one-time experiment, in an attempt to show their airline is "fun." It's a handy way to get people interested we get the feeling passengers learned more about life vests than they ever did before.
