Joker's Day

April Fools 2002 also referred to as “Joker’s Day” was a Toonami April Fools event in which the Joker infected SARA with a computer virus. The virus forced SARA to air four Joker-themed episodes of Batman: The Animated Series, instead of the regularly scheduled Toonami schedule. At the end of the fourth episode TOM is finally able to remove the virus by rebooting the system, thus returning control to SARA.
