The 'Cooking by the Book' meme originates from a musical number in the children's television show LazyTown, featuring the character Stephanie teaching viewers how to bake a cake. While the original song is wholesome and educational, it gained massive internet notoriety in 2008 through a viral mashup with Lil Jon's 'Step Yo Game Up.' This contrast between the bright, colorful world of LazyTown and aggressive rap lyrics created a lasting internet trope. The meme is now widely used to humorously illustrate following instructions to the letter, or conversely, adding an unexpected and often chaotic 'extra' ingredient to a standard process.
