Dr. Horrible:

A man's gotta do
What a man's gotta do.
Don't plan the plan,
If you can't follow through.
All that matters
Taking matters into your own hands.
Soon I'll control everything
My wish is your comman-

Captain Hammer:

Stand back everyone,
Nothing here to see.
Just imminent danger
And the middle of it, me.
Yes, Captain Hammer's here,
Hair blowing in the breeze.
The day needs my saving expertise.

A man's gotta do
What a man's gotta do
Seems destiny
Ends with me saving you
The only doom that's looming
Is you loving me to death
So I'll give you a sec to catch your breath

Dr Horrible (Spoken):
You idiot!
Captain Hammer (Also Spoken):
Dr. Horrible, I should have known you were behind this!
Dr Horrible (Spoken):
You almost Killed her!
Cap. Hammer(Spoken):
I remember it differently.
Dr Horrible (Spoken):
Is she--
Cap. Hammer (Spoken):
It's curtains for you, Dr. Horrible.
Lacy, gently wafting curtains.
Dr Horrible (Spoken):
Wh--

Penny (Singing):
Thank you, Hammer man
I don't think I can
Explan how important it was
That you stopped the van
I would be splattered.
I'd be crushed under debris
Thank you sir for saving me...

Cap. Hammer (Spoken then Singing):
Don't worry bout it.

A man's gotta do
What a man's gotta do
Penny: You came from above
Horrible: Are you kidding Hammer: Seems destiny ends
Horrible: What heist were you watching? Hammer: With me saving you Penny: I wonder what you're captain of Horrible: Stop looking at her like that!
Hammer: When you're the best Horrible: Did you notice he threw you into garbage!
Penny: My heart is beating like a drum.
Hammer: There's ass needs kicking, Sime ticking bomb to diffuse.
Horrible: I stopped the van! The remote control was in my hand!
Hammer: The only doom that's looming Penny: Assuming I'm not
Horrible: Whatever.
Penny and Hammer: Loving you to death
So please give me a sec to catch my breath
