"The Masquerade Party" is the eleventh episode of the sixth season of The Flintstones. It originally aired on ABC on November 26, 1965.


Fred and Barney enter a Royal Water Buffalo Lodge costume contest both dressed as devils. Meanwhile, a new band puts on a radio hoax saying the town is being invaded by space aliens called "Way-Outs". After deciding to let Barney be the devil, Fred decides to dress as a space alien and is mistaken for one of the Way-Outs.


  • The radio hoax the band pulls is somewhat similar to the 1930's radio program, War of the Worlds.
