It was played during the episode of the same name, while Phineas and Ferb attempt to identify the function of Doofenshmirtz's machine that had crash-landed into their front yard that morning.
Lyrics
What you gonna does when you don't know what it do?
Do, do, do, do, do, do!
It's way too big to be a buckle, and too bland to be a belly dancer!
Or when it tries to get your height it's never right unless you're three' foot two".
When you come or go, you can't tell if it waves goodbye or waves hello.
And in the library it's useless cause' it don't care when the books are due!
Do, do, do, do, do, do, do, do.
It doesn't seem to understand the game is not rock-paper-scissor-spaniel!
Instead of picking up the trash it started picking Lady Liberty's nose!
It makes a lousy baseball umpire or brow-wiper for bongo players!
And when it walks a dog it never really pays attention where it goes!
Do, do, do, do, do, do, do, do.
Do, do, do, do, do.
What do it do?
Continuity
- At the very beginning of the song, Phineas and Ferb can be seen doing the same walking dance as in the song, Technology vs. Nature.
Errors
- Isabella is hula dancing, not belly dancing.
