A character in the show Aqua Teen Hunger force that only appeared in the episode "Hand Banana". He would usually rape Carl on a regular basis throughout the episode.

Episode Plot: Frylock genetically engineers a dog for Meatwad using the "Make Your Own Dog 1.0" software, Carl's pool, and Master Shake's hand DNA. Meatwad names the dog "Hand Banana". The dog seems to be most interested in raping Carl. Hand Banana can speak so that his words are heard only by Carl, who is immediately unnerved by Hand Banana's clearly-menacing but initially-mysterious threat, "Tonight. You." Since Hand Banana's speech cannot be heard by Frylock, Master Shake, or Meatwad -- to them, Hand Banana plays the guileless, capering pup -- Carl appears either hallucinatory or simply deranged for the majority of the episode.

Carl creates his own genetically engineered dog. He names it "The Enforcer", though it prefers the name "Spaghetti". He orders Spaghetti to rape Hand Banana, but Spaghetti refuses, and instead rapes Carl along with Hand Banana. It turns out later in the episode that the software "Make Your own Dog 1.0" is illegal in most nations and has adverse side-effects, such as the dog forming a mental link with members of the owner's family (in this case, Hand Banana bakes goods in a successful attempt to butter up to Master Shake).
Some Hand Banana quotes:

"Tonight, YOU."

"Yeah, I'm just a dog."

"All I know is Ball, and Good...and RAPE"
