"One Hundred" is the twelfth and final episode of the seventh season of the animated television series Aqua Teen Hunger Force, and the 100th episode of the series overall. "One Hundred" originally aired in the United States on May 2, 2010, on Adult Swim. In the episode Frylock obsesses about the number 100 while Master Shake attempts to put Aqua Teen Hunger Force into syndication, until the episode abruptly turns into a parody of Scooby-Doo.

This episode marks the second time an Adult Swim original series made it to 100 episodes, the first being Space Ghost Coast to Coast. "One Hundred" strongly parodies the Hanna-Barbera cartoon, Scooby-Doo. This is the final episode of the series to premiere branded as an Aqua Teen Hunger Force episode before the series started using alternative titles for each season as a running gag. This episode received a positive review by Ramsey Isler of IGN, and was the third highest rated program the night of its debut. This episode has been made available on DVD, and other forms of home media, including on demand streaming.

Frylock is obsessed with the number 100. Master Shake then flies off to California to meet with television executives, and an animated version of Dana Snyder, the actual voice actor who provides the voice of Master Shake, pops out of him, demanding syndication money, claiming that it is the hundredth episode, so he deserves it. A television executive replies that because Aqua Teen Hunger Force is only eleven minutes long, they only have fifty half-hours of material. Dana Snyder then storms out of the room claiming that he'll be back in another eight years with another fifty half-hours of material ready.

Shortly after Master Shake returns home, One Hundred, a giant yellow monster in the shape of the number 100, appears and sends Master Shake, Frylock, and Meatwad into a different world, called "Aqua Unit Patrol Squad" which features the main characters in a Hanna-Barbera-like style. They investigate a haunted house, where Dr. Weird, a monster (whose costume Carl wore half naked on the Internet), Handbanana, Dr. Wongburger, the Cybernetic Ghost of Christmas Past from the Future, Billy Witchdoctor.com, and Willie Nelson all make brief non-speaking cameo appearances. Carl makes a brief appearance as well. They all run into a monster, soon after Frylock unmasks the monster, who turns out to be One Hundred in disguise. Shake tells him that he failed to put Aqua Teen Hunger Force in syndication, telling him that he even tried to double the episodes to make them fit in a half-hour time slot.

The closing credits feature Dana Snyder once again talking to a television executive, in an attempt to put Aqua Teen Hunger Force into syndication, but the television executive walks out on him, telling him that nothing he says is funny.
