Aqua Teen Hunger Force "Boston" (2008 Unaired Episode)

Following the 2007 Boston Bomb Scare (in which LED Mooninite signs placed as guerilla advertising for the show were mistaken for explosives),the creators made an episode titled "Boston" (intended as the Season 5 opener) as a response to the bomb scare, but were forced to pull the episode by Adult Swim to avoid any further controversy regarding the incident.

Not much is known about the episode, although series co-creator Dave Willis has revealed in an interview that 3 versions of the episode exist. Sadly, when asked if it would ever be released, Willis replied "yes, as soon as Boston gives us back our money", implying that there are no plans for it to ever see the light of day.
