Trivia: The anime TV series, originally scheduled to debut on Japanese television in October 2001, was delayed in respect for the September 11, 2001 terrorist attacks in the United States. The Japanese release of an anime TV series about teenagers fighting international terrorists was considered tactless so soon after the attacks against the U.S. by international terrorists. It was released January 8, 2002, three months after its originally announced premier date.
Trivia: Ozzy and Sharon Osbourne purchased a $6,300,000 mansion in Beverly Hills in 1999, three years before they starred in MTV's hit reality television show, "The Osbournes" (2002-2006). Bizarrely, the Prince of Darkness moved in next door to Pat Boone, the wholesome white bread Christian singing sensation of the 1950s and 1960s...and the two neighbors got on famously. Their neighborly friendship was such that Ozzy wanted to use Pat Boone's godawful 1997 cover of "Crazy Train" as the TV series theme song. MTV thought Boone would never agree to it, so they didn't even ask him; instead, MTV hired a Pat Boone impersonator to re-record the song. Later, MTV was amazed when Pat Boone himself said he would have gladly consented to them using his song, if they had only asked. Pat and Ozzy thought it was hilarious.
Trivia: Star Glenn Howerton partially credited "That '80s Show" as having helped get his popular sitcom "It's Always Sunny in Philadelphia" made. Despite this show failing and being cancelled after only one season, he was able to use some of the money me made from it to buy the camcorder that was used to the shoot the original proof of concept "pilot" that was used to pitch "Always Sunny" to networks. Without "That '80s Show," there's a very high chance "Always Sunny" wouldn't exist.
