Ted: Barney, the three days rule is insane. I mean, who even came up with that?
Barney: Jesus.
Marshall: Barney, don't do this. Not with Jesus.
Barney: Seriously. Jesus started the whole wait 3 days thing. He waited 3 days to come back to life. It was perfect. If he have only waited one day, a lot of people wouldn't have even heard that he died. They'd be all, "Jesus, what up?" And Jesus would probably be, like, "What up? I died yesterday". And then they'd be all, "Uh, you look pretty alive to me, dude". And then he would have to explain how he was resurrected and how it was a miracle. And then, the dude would be, like, "Okay, whatever you say, bro".
Robin: Wow, ancient dialogue sounds so stilted now.
Barney: And he's not going to come back on a Saturday. Everybody's busy doing chores. Working the loom, trimming their beards. No. He waits the exact right number of days... Three.
Ted: OK, I promise, I'll wait three days. Just please stop talking.
Barney: Plus, it's Sunday, so everyone's in church already. They're all in there, "Oh, no, Jesus is dead". Then, bam! He bursts through the back door, runs up the aisle. Everyone's totally psyched. And, FYI, that's when he invented the high-five. Three days, Ted. We wait three days to call a woman because that's how long Jesus wants us to wait. True story.

Robin: You have to go home and get to bed.
Barney: Oh, Robin, my simple friend from the untamed north, let me tell you about a little thing I like to call mind over body. You see, whenever I start feeling sick, I just stop being sick and be awesome instead. True story. Yeah, in two minutes, I'm going to pound a sixer of Red Bull, hop in a cab, play a couple of hours of laser tag, maybe get a spray-on tan. It's gonna be legen... Wait for it... [Barney falls asleep]

Marshall: Barney, I really don't think this is gonna help.
Barney: Do you know why you're not over Lily yet? It's 'cause you can still picture her naked. You can't get over a woman until you can no longer picture her boobs. It's a scientific fact. The average male brain can only store a finite number of boob images, or BPEGs and your hard drive's filled to capacity with Lily's.
Marshall: There are a lot of them.
Barney: They won't go away until you overwrite them with images of other women's boobs. Now, this journey may take as many as a million boobs so we begin here tonight my friend. Two at the time. Those count as four.

Barney: I didn't get your message until I woke up. Bro, I am so sorry.
Marshall: Thanks.
Barney: I know it must be tough. But are you ready to hear something that will not only make you feel better, but will actively excite you?
Marshall: Sure.
Barney: For the first time ever, the three of us are single at the same time. I've dreamed about this day, boys, and it's going to be legendary! Together, we will own this city. Any time, a girl wants to get back at her ex-boyfriend, we'll be there. Anytime a girl wants to solve her father issues through promiscuity and binge-drinking, we will be there. Anytime a bachelorette party drives through the city in a limo sticking their heads out the sunroof, shouting "What's up New York?", we will be what is up New York! Gentlemen, we are about to embark on... [Barney looks at Robin, then Ted] Oh man, you guys did it, didn't you?!

Future Ted: [v.o.] One thing I learned that summer is that when love is beginning and love is ending, the first thirty days are remarkably similar. For one thing, you spend most of the time in bed. Your friends can't stand to listen to you. And you never seems to wear pants.
