One Good Scare

 was the song Phineas sang as he ran through his haunted house when Isabella had the hiccups in "One Good Scare Ought to Do It!"

Lyrics
Phineas: Come, let's tip-toe into the dark (La la la la la la la la)

One good scare oughta do ya!

You'll find our bite much worse than our bark!

One good scare ought to do you some good!

If you should find the daily grind a tad bit taxing on the mind; to help unwind if so inclined, I have a small suggestion...

That if you dare into my lair, you should prepare for quite a scare!

But "Will you share in this nightmare?" would be my only question.

Baljeet: ''Boo! Boo, I say!''

Phineas: Baljeet?

Baljeet: ''Oh, I am not Baljeet. I am the scariest thing known to man: a failed: math test.''

Phineas: ''Yeah, right. We're just gonna move on now.''

Baljeet: You can run, but it won't be to the college of your choice, I tell you!

Phineas: If your hair lies lifeless and limp, one good scare oughta do ya!

Come with me, now, don't be a wimp!

One little scare ought to do ya some good.

Phineas: ''Hello? Buford?''

Buford: ''Behold... the face of evil.''

Phineas ''Buford, are you supposed to be Jeremy's little sister? You said you were gonna be something scary!''

Buford: ''She is scary, man. She gives me the willies.''

(music stops)

Phineas: Little Suzy Johnson gives you the willies.

Buford: You don't know man, you don't know!

Phineas:: ''Uh... we'll catch up to you later, okay?''

(Music Continues)

Buford: ''Wash away the horror. Wash away the horror.''

Singers: La, la, la, la, la, la, la, la, la

La, la, la, la, la, la, la, la, la

Phineas: That is quite right, I would delight in taking flight into the night.

If I may give you such a fright, you know I surely would!

But if I seem a bit extreme in my attempts to make you scream,

Remember that this spooky scheme will cure...

Your hiccups...

For good!

Singers: La, la, la, la, la, la, la, la, la

Spooky Faces: One little,

One little,

One little,

One little...

Phineas & Spooky Faces: One little scare oughta do you some good!

Ferb: (Deep, diabolical laugh)
