'How I Met Your Mother' Storylines That Were Never Resolved

Something we never learned about this series was what exactly killed the dinosaurs... er, I mean the titular mother.

What was so serious that she ended up dying and ruining the series end?

I know that's a lot of apostrophes in one sentence, but this unsolved plot thread is still valid.

Shouldn't we know who No. 31 is? Did Barney get full custody? If so, shouldn't we have seen him get that?

Who was this strange and mysterious character that yelled at Barney's boss, then went on to kill himself?

Sure, we know that Marshall meets him at some point, but was Barney making the rest of it up?

Listen, we know that the series is called How I Met Your Mother, not How I Met Your Mother And Some Other Stuff That Happened, but I want to know about Marshall's time in Rome!

I refer you to my previous comment about the title of the series, however, it would've been nice to see how Tracy ended up being Ted's soulmate.

At least a little more of that.

In one episode, he says he can't fight and has never been in one.

In another, he says he's fought with his brothers a whole lot. Which is it, Marshall? Show us, HIMYM writers!

We know that Lily's father would "never pay for another wedding" and that he's a game board designer (a failed game board designer) but how did they get to that point?

Speaking of Lily's parents, how come we see so little of Lily's mom throughout the series?

We see Mickey (Lily's dad) a bunch of times throughout the series, but her mom only once or twice.

Do you remember her, Ted? The lady that was supposed to sing at your wedding?

Of course not, poor old lady, she's probably sitting by the phone right now waiting for a call...

I mean, probably not, because she died of a nondescript disease, but couldn't we have seen at least a little bit of what happened to the band after she passed away?

Speaking of No. 31, does Barney just... die alone? A single father?

Sure, he has a daughter now, but will he ever find someone to help him parent this lost child?

At the end of the series, Ted just becomes Josh Radnor, even though Bob Saget has been narrating this whole time.

Shouldn't he be Bob Saget? Maybe this is a Full House spinoff?

We know that Lily and Marshall move out to the dreaded suburbs, but one question rings through our minds after that move.

Considering how much damage was done to the apartment through sword fights, did Marshall get his security deposit back?

Ted loves marriage. If he had a shield, it would read 'Marriage, Soulmate, and Marriage'. So why the wait?

Maybe he was maturing? Then again, he shows up at Robin's with a blue french horn, so probably not.

What happened with the bloody pineapple? This is the only one fans really care about. You have got to finish the darn story, Trudy!

(P.S. You get to see what happened in the DVD box set).
