I love it. I love Barney. I want to change my name to Swarley. Which brings me to the main point of today's post.
I google'd Swarley because I wasn't sure of the spelling (-y/-ey?). One of the results was a wikipedia page that talks about all the tie-ins.
There are websites for Marshall and Lily's wedding (a bit ruined by the show plug in the top right corner), a Pro-Swarley-name site.
And then we get to TedMosbyIsAJerk.com. W...ow.
Yes, that *IS* a 20-minute song about what a jerk Ted Mosby is. It also ends with a reverse easter egg.
(also, random BSG reference at ~13:30 made me laugh)
