Cast

Lyrics
Phineas Flynn: What makes a fly fly? What makes a flower flower? What makes a duck duck like a duck? And look at that tower tower.

Clyde Flynn: Hey, what makes a leaf leaf? And crows crow instead of singing? A chime knows the time to chime like a chime And how does a swing know swinging?

Phineas Flynn: Everything just seems to know Exactly what to do.

Clyde Flynn: But as for how they know it I haven't got a clue. Listen, Phineas, let's let the fly just fly. And let's let the flower flower. Just let the duck duck like a duck. And let the big tower tower.

Phineas Flynn: Sometimes you don't ask why. Sometimes it's nice to see.

Clyde Flynn: We don't have to get the answers yet. We'll just let the bee just bee.

Phineas Flynn: We'll just let the fly and the flower and the duck.

Clyde Flynn: And the tower and the leaves and the crow and the chime.

Phineas Flynn: And the swing and the little buzzing bee...

Phineas Flynn and Clyde Flynn : Just bee! Just bee!

Clyde Flynn: (spoken) Just bee, Phineas!
