How I Met Your Mother, Season 6

[Barney has just called dibs on a hot girl Ted asked him to make a short glance at. Ted is not amused]

Ted:
You can't call dibs on a girl that I've been sitting here thinking about eventually talking to at some point!

Barney:
You never called dibs.

Ted:
Dibs were implied!

Barney:
"Implied" dibs?

Ted:
Yeah.

Barney:
Ted, you are spitting on the grave of Sir Walter Dibs, inventor of the dib. It was 1652, the SS Dibs was lost at sea-

Ted:
I don't have time for a fake history lesson, so I'll keep [points pen at Barney] this simple: You go over there and talk to that girl, I'll see you in court.

Barney:
Who's gonna represent you? Dibs-on-Marshall's-my-lawyer!
