ok i just love these sort of things.... lets make something up:
Kid Buu: Goku, it is time I annihilated the Planet Earth. You and your collection of Saiyan and Half Saiyans, and Quarter Saiyans, and occasional Nameks, or Namekians, depending on which plural you prefer, are starting to irritate me, and cause me overall unpleasant thoughts, leading to destructive behavior. The only way to cease such behavior will be to dispose of the cause, hence being the above mentioned Races of interplanetary Protagonists. Now, please sit quietly, while my well-orchastrated plan for world domination takes it perfectly-timed course and releaeses all this unneeded stress from my artificially-created life. Thank you for your cooperation.
[hehehe i loved this one. the only thing kid buu used to say was: hehehehe
