John Jacob Jingleheimer Schmidt is a traditional American children's song that has been sung in schoolyards and at summer camps for generations, usually as a round that gets quieter and then louder again. Its joke is simple: one ordinary boy's long name gets shouted by an entire crowd, followed by a nonsense da-da-da refrain everyone can join. The tune resurfaced online as a meme for exaggerated entrances and name gags, in the same spirit as the John Cena entrance meme, and the clip's tags tie it to the cartoon Recess, whose playground world made the chant feel right at home.
