The Bumpers, or "Bumps" for short, which are shown before and after each commercial break, were originally shots of senior citizens swimming and doing random pool-related activities in public pools. The lifeguard is often heard talking through a megaphone and saying things such as "Adult Swim, all kids out of the pool!", and announcing the forthcoming TV show. The logo was, basically, "ADULT SWIM" written in large red capital letters. On Saturdays, the shows were announced by a computer generated voice. Adult Swim's theme music was "D-Code", performed by Melbourne artist Dust Devil. The song was a remix of "Mambo Gallego" by Tito Puente, Sr.
