what'cha doin'?

Phineas & Ferb

I'm just the curious girl 'cross the way
Every day I come over, and here's what I say

What'cha doin', what'cha doin'?
What's the day's activity?
What'cha doin', what'cha doin'?
By any chance, could it include me?

What'cha doin'? What'cha doin'?
(What'cha doin'?)
I don't mean to disturb
What'cha doin', what'cha doin'?
(What'cha doin'?)
You know it's not really directed at Ferb
When I say-ay-ay-ay-ay
What'cha doin'?

Don't you know, Phineas, you have no idea
That every day I'm just dyin' to see ya?
And say

What'cha doin', what'cha doin'?
(What'cha doin'?)
I really wanna know
What'cha doin', what'cha doin'?
(What'cha doin'?)
Can I be part of the show?
When I say-ay-ay-ay-ay
What'cha doin'?
