From the Phineas and Ferb original TV soundtrack
Lyrics:
CANDACE:
Psst! Mom!
MOM:
Candace, have you been near the wild parsnips again?
CANDACE:
Yes, but you gotta see what Phineas and Ferb are doing!
MOM:
What is it now?
CANDACE:
Those boys are always up to something
And it's bringing me to tears
'Cause just before you get home
It always just magically disappears!
Those boys are evil!
But before you get home
They somehow always clean up the mess
Those boys are evil
Let me spell it out for you, mom
E-V-I-L B-O-Y-S
They built a roller coaster
And a beach in the backyard
Drove cattle through the city
And messed up the boulevard
They took me back in time
When we went to that museum
They built fifty-foot treehouse robots
But still you didn't see 'em
Those boys are evil
Their crazy shenanigans cause me all kinds of distress
Those boys are evil
Sing it with me!
E-V-I-L B-O-Y-S
I know you think they're saints
But mom I'm here to tell
Those B-O-Y-S
They're just E-V-I-L!
Those boys are evil
They're making me feel like my head's in a hydraulic press
And that don't feel too good
Those boys are evil
Everydody!
E-V-I-L B-O-Y-S
That's what I'm talking about
E-V-I-L B-O-Y-S
That's right those boys
Are evil little boys!
