'Home Wreckers' - Season 5, Episode 20
Ted reacts badly to his mother's second wedding, culminating in him buying his "dream house". Meanwhile, the gang try figure out whether Barney or Robin cried at the wedding.
Air Date: April 19th 2010.
Lily: What do you mean, you bought this house?
Ted: I mean, I made a bid online, I won the auction the next day, and got approval! I just finalized the paperwork.
Barney: And was the Blair Witch easy to deal with, or did she haggle over the closing cost?
Marshall: Don't even joke about that, man!
Future Ted: I didn't give up on my dream house, because that's the thing about stupid decisions; we all make them, but time is funny and sometimes a little magical. It can take a stupid decision, and turn it into something else entirely. Because kids, as you know, that house ... is this house.
Ted: I'm gonna put a grill out here. Every Sunday, right here, it's gonna be a total sausage fest.
