This meme started in 2008, however was based off of an episode of the popular children’s cartoon, “Spongebob Squarepants” entitled, “The Secret Box”, in which Spongebob tries to figure out what’s in his friend Patrick’s secret box. The scene of origin is in which Patrick tells Spongebob he can look inside, only to find that there is only a string. The meme is that when Spongebob opens the box, there will be something shocking or of comic relief inside replacing the original string.
