July 7 is a big day for astronomers, conspiracy theorists and David Duchovny fans, as it's the supposed day that flying saucers were spotted over Roswell, New Mexico in 1946. Without the Roswell incident (wherein people thought the government was covering up the fact that they found wreckage and bodies from a fallen UFO), we wouldn't have gotten "The X-Files," "Independence Day" or Foo Fighters.
Today also marks the Michael Jackson memorial in Los Angeles, and the best example of aliens and MJ coming together is the Alien Ant Farm cover of "Smooth Criminal." The song was the first major hit for the band, who performed it live before the Video Music Awards in 2001. "How many of you guys like Michael Jackson?" asks frontman Dryden Mitchell. Answer: Hundreds of thousands of us.
