The Office2005

Jim Halpert:
Do you remember what you said to me on my first day of work, just before you walked me over to my desk?

Pam Beesly:
Yeah. "Enjoy this moment, because you're never going to back to this time before you met your desk-mate, Dwight."

Jim Halpert:
And that's why I knew. You?

Pam Beesly:
You came up to my desk, and you said, "This might sound weird, and there's no reason for me to know this, but that mixed-berry yogurt you're about to eat has expired."

Jim Halpert:
That was the moment that you knew you liked me?

Pam Beesly:
Yup.

Jim Halpert:
Wow. Can we make it a different moment?

Pam Beesly:
Nope.
