"It was 1652. The S.S. Dibs was lost at sea..."
Unfortunately, Barney is unable to continue the story, as Ted interrupts him, claiming he doesn't have time for a fake history lesson.
Later on, Ted bought "dibs" on the "bar-girl" from Barney for $20, after turning down Barney's initial offer of $250,000, as well as getting a chance to at least "smell her". Shortly after, Barney and Ted realize that the bar-girl was actually a possible lesbian/bi-sexual, who was currently engaged in a potential relationship with Ted's (short-time) ex-girlfriend Cindy, with whom Future Ted reveals she had a daughter.
important note: in the episode The Pineapple Incident Lily calls a "no dibs" on cleaning teds puke implying the opposite of a dibs
