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.
SpongeBob: [spoken] I call this one the Campfire Song Song. [SpongeBob playing the ukulele]
Let's gather 'round the campfire and sing our campfire song
Our C-A-M-P-F-I-R-E-S-O-N-G song.
And if you don't think that we can sing it faster then you're wrong, But it'll help if you just sing along.
Patrick: Bum, bum, bum....
SpongeBob: [sings extremely fast]
And if you don't think that we can sing it faster then you're wrong,
But it'll help if you just sing along
Patrick:[in the background, struggling to keep up]Sing another song!
SpongeBob: C-A-M-P-F-I-R-E-S-O-N-G song, Patrick!
Patrick: Song! C-A-M-P-F-I-R-E...
SpongeBob: Squidward! [Squidward keeps silent and just stares at them.]
It'll help! It'll help!
If you just sing along! [Fireworks] [smashes ukulele] [Patrick slams a drum on SpongeBob]
