The use of a multiply repeated phrase is a device that was often used by Charles Schulz in the Peanuts strip. In this case, I just wanted to say “it made me grow big boobs” as many times as possible. The reference to the manual is a tip of the hat to the movie Mystery Men. There is a scene where the heroes are examining a non-lethal weapon invented by a mad genius and one of the characters says “Oh, look, a manual!” It strikes me as very funny that an inventor would go to the trouble of writing a huge manual for an experimental device.
