Disney's Phineas and Ferb: Early indoctrination in the Police State of mind??

My son turned 6 last week and received a cute Phineas and Ferb birthday card that plays music when it's opened.

I finally had the opportunity to pay attention to what song plays from the card, mainly because my sons are walking around singing it all day. It has quite an infectious chorus. Anyways, the lyrics go like this:

I can see the things you doing
And you think that I'm naive
But when I get the goods on you
She'll finally believe

She says it's all just drama
But every bubble's got to pop
She's gonna see just what your doing

And then you're finally gonna have to STOP!
Don't think you're gonna win this time
'Cause you better believe I'm gonna drop a dime
On you

I'll get ya! yeah! I'll get ya!
And when I do you're gonna be Busted!
BUSTED!
I don't wanna put the hurt on you
But you better believe me when I tell you
That I finally got the dirt on you

YOU'RE BUSTED! (busted! )
Yeah, she's finally gonna see the light
This is how it's gonna be
When she finds out that I was always right

YOU'RE BUSTED!

There's a new cop on the beat
And I'm bringing down the heat
My eyes are wide to all your lies, cause you're not that discreet
And I don't care what you've heard
'Cause there's one six letter word
It's gonna set me free
(Gonna set me free)
It starts with a b
(Starts with a b)
It goes B-U-S-T-E-D you are BUSTED!

I don't wanna put the hurt on you
But you better believe me when I tell you
That I finally got the dirt on you
YOU'RE BUSTED
[Think you're gonna win this time]
Yeah, she's finally gonna see the light
[Drop a dime on you]
This is how it's gonna be
When she finds out that I was always right

YOU'RE BUSTED!
