Between 4:00 am and 5:00 am on December 21, and December 30, 2000 (while Space Ghost Coast to Coast was on hiatus), several new Williams Street series made unannounced "stealth" premieres. Sealab 2021, Harvey Birdman, Attorney at Law, Aqua Teen Hunger Force, and The Brak Show all premiered unannounced; the official schedules listed the shows as "Special Programming". Prior to that, in Entertainment Weekly, it was stated that Michael Ouweleen's next project was working on the Harvey Birdman, Attorney at Law Pilot with J. J. Sedelmaier. In a 1999 interview, the indie pop rock band Calamine stated they had recorded the theme song for Sealab 2021. While entertaining pitches for a variety of adult cartoons, Lazzo realized the potential for packaging them as a complete adult-focused block. Different names were considered, including “ibiso”, which was said to be Spanish for “stop”, and “Parental Warning", "Parental Block" but he eventually settled on "Adult Swim". Cartoon Network was ready to launch the adult animation block on April 1, 2001 but was later delayed and aired five months later. In June 2001, TV Guide had recorded an interview with Cartoon Network's former president, Betty Cohen. She stated there was a new programming block coming out in September that was aimed for an adult audience. During this month at the Cartoon Network Confidential, "Cartoon Network's best originals and outrageous animated shorts for discriminating adults" in New York City, an upcoming episode of Space Ghost Coast to Coast titled "Kentucky Nightmare", the stealth pilots from December, Captain Linger, and an episode of Home Movies were screened for free. The screening was part of the Toyota Comedy Festival. On Saturday, July 21, 2001, the Space Ghost Coast to Coast panel at San Diego Comic Con had a trivia game in which the winners won a promotional CD that had the theme songs to the upcoming Adult Swim Shows. Everybody who attended got a free Adult Swim t-shirt that was packaged to look like a roll of bandages that a lifeguard might carry.
