The "Campfire Song Song" is a song sung by SpongeBob in the SpongeBob SquarePants "The Camping Episode". Patrick sings along with him as it goes on, but he cannot catch up because SpongeBob is singing far too fast, so he instead resorts to playing the drums near the end.
SpongeBob: I call this one, the Campfire Song Song.
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: C-A-M-P-F-I-R-E S-O-N-G song!
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: (...Singing our 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! ... Good!
It'll help, it'll help!
If you just sing along!
