The Big Bang Theory, Season 6

Sheldon:
One vintage Mister Mxyzptlk action figure. That's Leonard's.

Amy:
Children's toy.

Sheldon:
One Star Trek: The Next Generation Phasor. That's Leonard's.

Amy:
Children's toy.

Sheldon:
One Game of Thrones collector's edition long claw sword. Ah, Leonard and I bought that together. That's a bit of an ethical conundrum. Eh, I'll keep it.

Amy:
So, what's your plan moving forward?

Sheldon:
I suppose I'll have to find and cultivate a new roommate. What a task that will be. Do you know how uncivilized Leonard was when I took him in?

Amy:
No.

Sheldon:
It took me forever to get him on a bathroom schedule. He would go whenever the mood struck him.

Amy:
Like a dog boy.

Sheldon:
Exactly.

Amy:
What if you could find a roommate who was a scientist and already familiar and comfortable with your ways?

Sheldon:
That would be ideal. If a person like that existed I would sign on no further questions asked.

Amy:
Great! Here I am!

Sheldon:
Wait. Here who is where?

Amy:
Me. Aren't I your perfect roommate?

Sheldon:
Um.

Amy:
Think about it, Sheldon. I'm not a stranger. We're intellectually compatible. I'm willing to chauffeur you around town. And your personality quirks which others find abhorrent or rage-inducing I find cute as a button. What do you think?

Sheldon:
Um.

Amy:
Tell me one reason that this isn't a fantastic idea.

Sheldon:
Um.

Amy:
See, you can't. I'm going to see if Leonard's room is big enough for my water bed.

Sheldon:
Um.
