[Intro: Mike Myers, Sean Hayes, Spencer Breslin & Dakota Fanning]
Maestro!
I
Know it is wet and the
Sun is not sunny, but
We can have lots of good
Fun that is funny! It's
Fun to have fun but ya
Got to know how...
Bleurgh! (Ugh...)
Hairball!
I know
Lots of good tricks, and I'll—
Stop! This! Right! Now!
The fish is talking!
This cat should not be here, he should not be about!
He should not! Be here! When your mother! Is out!
Come on kids, you're gonna listen to him?
He drinks where he pees!

[Verse 1: Mike Myers]
There was this
Cat I knew back home where
I was bred, he never
Listened to a single thing his
Mother said! He never
Used the litter box, he made a
Mess in the halls, that's why they
Sent him to a vet to cut off
Both his ball—
Ba... ba...
[Chorus: Mike Myers]
BOY! That wasn't
Fun, fun, fun!
He never learned you can have
Fun, fun, fun!
But less is more! They may
Ship you off to school, so rain it
In a little, we
Can't spell fun without you in the
Middle! (Bah-bah-bah-bah-bah-bah-
Bah!)

[Post-Chorus: Mike Myers, Sean Hayes]
Children!
This cat is currently in violation of 17 of your mother's rules!
City Morgue!
18!

[Verse 2: Mike Myers]
There was this
High-strung cat who thought she
Knew it all, the way she
Scheduled out her day could drive you
Up the wall! She liked to
Be the teacher's pet, always the
Head of the class, and took a
Ton of TNT to kill the
Bug up her a—
A... a...
[Chorus: Mike Myers]
ASK! Me was she
Fun, fun, fun?
Not a chance, you can't have
Fun, fun, fun!
If you're uptight, so loosen
Up and lose those lists, life isn't
Such a riddle, you
Can't spell fun without YOU in the
Middle!

[Bridge: Mike Myers]
You can
Juggle, work and play, but you
Have to know the way! You can
Keep afloat a wish, like the
Way I do this fish! You can
Be a happy fella, someone
Throw me that umbrella! And that
Rake! That cake!

[Chorus: Mike Myers]
That's what you make it, so have
Fun, fun, fun!
Go insane and have some
Fun, fun, fun!
Just look at me!
Fun, fun, fun!
No more rain, look! It's a
Sun, sun, sun!
So can't you see? I'm as
Happy as a clam, I'm as
Fit as a fiddle! Yeah, the
Dogs may bark about you, and the
Pure-bred cats may doubt you, but re-
Member this, you can't have fun with-
Out you in the
Middle!
[Outro: Sean Hayes]
Bravo, cat...
