Dumber Days.Frylock finds Master Shake and Meatwad in Carl's backyard, and is alarmed to see a bone sticking out of Meatwad, believing it's one of his. Meatwad tells Frylock that he took his brain out to polish it, and forgot where he put it, so he has had to stick a rotisserie chicken in there. Shake has the brain, however, and is using it for "undercover aquatic training." Frylock rips it away from Shake, and discovers the truth... Meatwad's brain is a cat toy! Upon discovering this, Meatwad suddenly becomes both depressed and unaware of his surroundings. First, Carl throws him out of his window after Meatwad mistakenly thought his bedroom was his, and then he spends the next three days in the doorway of the Aqua Teens' house while ants crawl and build anthills around him. Frylock tries to convince him to come in, but Meatwad says that time and space are a mystery to him because he doesn't have a brain. Frylock decides that the best way to make Meatwad feel better about himself is to find him a new brain. After Frylock measures the circumference of Carl's skull, Carl catches on and decides to give his friend Terry a call (the same Terry that Dr. Weird called earlier) and get a brain on the black market. Said brain arrives on the Aqua Teens' doorstep in a cooler the next day. Frylock apparently puts the brain into Meatwad's head, and the results are obvious. Meatwad's brain and body slowly grow and grow until they both are ridiculously huge and Meatwad's intellect grows to match.
