How I Met Your Mother, Season 8

[Lily and Marshall ask Ted why he wants them to bring their old beanbag chair to Italy]

Lily:
Ted, if this means so much to you, why don't you just take it for yourself?

Ted:
No, it's important that you keep it.

Marshall:
Why?

Ted:
This is the first thing we bought when we moved here after college. It was the only piece of furniture we had for a week, and now you two are moving to Italy. What if our friendship doesn't pass the "Have you used it in a year?" test? If you can throw out this chair, who's to say you can't throw me out too?

Marshall:
That could never happen.

Lily:
You're not a chair, you are our best friend.

Ted:
You can say that, but a lot can change in a year.
