Dr. Horrible:
man's gotta do
what a man's gotta do
Don't plan the plan
if you can't follow through
All that matters's taking matters
into your own hands
soon I'll control everything
My wish is [bad word] 

Captain Hammer:
Stay back everyone
nothing here to see
Just imminent danger
in the middle of it, me
Yes Captain Hammer's here
hair blowing in the breeze
the day needs my saving expertise

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
I'll give you a sec to catch your breath

Penny:
Thank you Hammer Man
I don't think I can
explain how important it feels
that you stopped that van
I would be splattered
I'd be [bad word] under debris
Thank you sir for saving me

Captain Hammer, Penny, Dr. Horrible:
(spoken: "Don't worry about it")
man's gotta do
what a man's gotta do/ You came from above/ Are you kidding?
Seems destiny /What heist were you watching?
ends with me saving you/ I wonder what you’re captain of/ Stop looking at her like that!
When you’re the best/ I must be in shock
You can’t rest, what’s the use/my heart is beating like a [bad word]  Did you notice that he threw you in the garbage?
When [bad word] needs kicking/ I stopped the van
Some ticking bomb to defuse/ the remote control was in my hand!
The only doom that's looming /only doom that’s looming
is you loving me to death/ is me loving you to death/ What-ev-er
so please give me a sec to catch my breath/so please give me a sec to catch my breath
Balls.
