Well, if it is the end for Flight of the Conchords, the series, the final episode is a great way to finish off a tremendous two-season run.

(And we all know it’s not the end for Flight of the Conchords, the band, who’ll be playing Coral Gables’ BankUnited Center on April 7. )

But the potential end of the show contained two of the best plotlines in the series’ entire run — Mel and Doug’s marriage crashing to earth, and Murray creating a musical of Bret and Jemaine’s experience.

The boys are evicted from their apartment when their landlord discovers they had been paying with New Zealand dollars, rather than U.S. bucks. (And the fact that Eugene, the landlord, uses a calculator watch to figure out their back rent was priceless.)

Mel gladly takes them in (Doug, not so much). And, certainly to no fan’s surprise, basically traps them in her home. This in turn leads to the weakest point of the episode, where Bret’s nightmare morphs into the song, “Petrov, Yelyena and Me,” a song of cannibalism that may be one of the duo’s weakest.

But to see Mel explain how she and Doug are splitting up as if Bret and Jemaine were to become the children of divorce. (And they flash to Doug’s post-breakup life in an RV reverting to his partying ways. Which is the happiest we’ve seen him all season.)

Meanwhile, Murray continues to work on his Conchords musical — in which he confuses bits of Bret’s New Zealand childhood with that of Luke Skywalker’s on Tatooine. (Murray cuts those scenes, which once again disappoints Greg, who seems to have worked very hard on a landspeeder model.)

They iron out the rough edges and present it to Murray’s colleagues from other embassies, and somehow, ends up getting the boys — and himself — deported back to New Zealand.

Will I be sad to see the boys ride off into the sunset on Murray’s tractor in a sheep paddock? A little. But it could end here, and I would say it was one heck of a run.
