As previously spoiled by us, last night was Laura Prepon's final appearance on How I Met Your Mother as Ted's college girlfriend, Karen.  So what went wrong with Karen and Ted?  Well, for starters, Karen failed Lily's front porch test.

What happens when you fail the front porch test?  You get sabotaged, of course!  There were also plenty of revelations made by character in the episode and you can find them out in our "The Front Porch" recap.

Now, enjoy some pictures of what the gang will look like in forty some odd years by clicking to enlarge any of the following thumbnails:

Sorry guys, Barney just didn't make the front porch test, but he did help contribute to some of our favorite quotes from the episode:

Barney: So you're this comfy every night and Lily still has sex with you?
Marshall: Yeah, that's what marriage is all about, man. Unconditional love. You can wear whatever you want and still get laid | permalink

Robin: Let's make a pact, if we both turn 40 and we're both single..
Ted: Robin Scherbatsky, will you be my backup wife?
Robin: A girl always dreams of hearing those words. Yes, yes, a million times, yes! | permalink
