[Intro: CG5, Swiblet]
It's not about winning, it's about fun!
What's that?
Fun is when you- fun is- It's like- it's kind of-
Sort of like a- What is fun? I-
Let me spell it for you!

[Chorus: CG5]
F is for friends who do stuff together
U is for you and me
N is for anywhere and anytime at all
Down here in the deep blue sea!

[Verse 1: Swiblet]
F is for fire that burns down the whole town
U is for uranium... bombs!
N is for no survivors when you-

[Bridge: CG5, Swiblet]
Plankton! Those things aren't what fun is all about!
Now, do it like this
F is for Friends who do stuff to-
Never! That's completely idiotic!
Here, let me help you...

[Chorus: CG5, Swiblet]
F is for friends who do stuff together
U is for you and me (try it!)
N is for anywhere and anytime at all
Down here in the deep blue sea!
[Interlude: Swiblet, CG5]
Wait...I don't understand this...I feel all tingly inside...
Should we stop?
No! That's how you're supposed to feel!
Well, I like it! Let's do it again!
Okay!

[Verse 2: SpongeBob & Plankton]
F is for frolic through all the flowers
U is for ukulele
N is for nose picking, sharing gum, and sand licking
Here with my best buddy

[Outro: Both]
Ha, ha, ha, ha, ha
Ha, ha, ha, ha, ha
Ha, ha, ha, ha, ha
Ha, ha, ha, ha, ha
Ha, ha, ha, ha, ha
Ha, ha, ha, ha, ha
