As much as we love 'How I Met Your Mother' we have to admit that when a sitcom stretches on to eight seasons at about 22 episodes a pop, a lot of the past gets lost in the shuffle.  But with 'How I Met Your Mother' season 8 (potentially) to be the last, we're due for a quick refresher, no?  Thankfully, Neil Patrick Harris is once again our savior as a new clip from 'HIMYM' premiere "Farhampton" brings us back up to speed!

When the first promos for 'How I Met Your Mother' season 8 started hitting the web, they revealed a terrible secret: Lily accidentally spills the beans about Barney and Robin's past relationship in front of his fiancee Quinn (Becki Newton)!  But for many tight spots as the Barnacle has gotten his way out of (and let's face it, into), how will Quinn forgive him for this one?  A quick rundown of the last eight years should do it.

Thanks to Entertainment Weekly, the first official clip from 'How I Met Your Mother' season 8 premiere "Farhampton" catches both Quinn (and us forgetful viewers) up on the entire dating history of the series, in a staggering 60 seconds!  But the real questions (apart from how Neil Patrick Harris doesn't pass out) is, will it be enough for Quinn to forgive him?  Does it even matter, since we know - SPOILER ALERT - Robin to be the eventual bride on his wedding day?

Head over to Entertainment Weekly to check out the clip, and tune in for the premiere of 'How I Met Your Mother' season 8 on CBS Monday, September 24!
