The series finale titled "Last Forever," like most HIMYM episodes, will fiddle with the timeline. "We're a very time-jumpy show, so you will see a lot of the future and where everyone is in the end," HIMYM boss Craig Thomas says. But when questioned if the end will be like past 2030? Thomas hinted "Well, that is the future!" he says with a wink.
Thomas also admitted that he and co-creator Carter Bays haven't written the finale yet, but "we know what the last minute or two is like."
How do you want the series to sign-off?
