Marshall and Mary in “Unfinished Business”

Marshall

No. Not exactly. Look, it's nothing like what you think.

Mary

Oh yeah? Well you should probably explain, because I'm pretty confused. I know you love the job and I thought you—I thought we were friends.

Marshall

We are. You're my best friend.

Mary

Jesus, Marshall, you're like my only friend.

Marshall

I know, and you're like my only friend.

Mary

So? Sounds like a pretty good arrangement. What's the problem?

Marshall

The problem with us is—

Mary

Please just tell me.

Marshall

I feel like I'm the keeper of this exotic animal, and I spend my time either protecting you from the world or the world from you. And it's just—it's a lot of responsibility.

Mary

I'm sorry. But that's your job. [Kisses him on the cheek] And you cannot quit.

Marshall

Okay.
