NBC Scrubs Episode - January 30, 2003. A song was playing at the end
of the episode when one of the doctors was on his knee proposing to
the nurse. Sounded like Green Day or someone similar...

Who is it, and what is the name of the song? 

Oh, the lyrics...

Someday someone is going to ask you a question that you should say yes
to...

Hi there,

The song in question is "Question" by the Old 97's
http://www.sing365.com/music/lyric.nsf/SingerUnid/DEBB34F9C2B98A6448256A2C0005715E

It appears on their album "Satellite Rides".

Question
--------

She woke from a dream
Her head was on fire
Why was he so nervous?

He took her to the park
She crossed her arms 
And lowered her eyelids

Some day somebody's gonna ask you
A question that you should say yes to
Once in your life
Baby tonight I've got a question for you

She'd had no idea
She started to cry
She said "in a good way"

He took her by the hand
Walked her back home
They took the long way

Some day somebody's gonna ask you
The question that you should say yes to
Once in your life
Baby tonight I've got a question for you

I've got a question for you


Search strategy: question "say yes" lyrics

This is the first time my answer to a question has been "question"!

Thank you thank you thank you!!! You've provided much mental relief to
me. I'm a great websearcher, I just never thought to even try it with
so few search words. Now I know.

And I'm glad I could provide your first "Question".

Thanks again!
