"Campfire Song Song" is a song that SpongeBob sings in the episode "The Camping Episode." Patrick was also singing too, but he could not catch up because SpongeBob was singing far too fast, so Patrick resorted to playing the drums near the end.

On the year of it's release in Australia, Nickelodeon Australia made a competition for all kids around Australia, which was whoever could sing the song fastest (by taking a video of themselves singing it and posting it for the competition).
This song is the most known song in the series, and has been featured in many films, and other TV series. One example is in the Family Guy episode "Road to Rupert," which was also directed by Dan Povenmire, in which Peter Griffin watches the episode's scene were SpongeBob and Patrick sing the song.
