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]

Barney: We're going to Sascha's.
Ted: Who the hell is Sascha?
Barney: Sascha. [points to security woman] She's having friends over for drinks at her house. It's gonna be legen- wait for it, and I hope you're not lactose intolerant 'cause the second half of that word is -dairy!

Barney: [slurring] A few final thoughts. Don't get married until you're 30. Play laser tag once a week. Give at least as many high fives as you get. Teacup pigs are lady magnets, but very hard to care for. Not worth the effort. The same goes for dogs and babies. And most importantly, whatever you do in this life, it's not legendary unless your friends are there to see it. Good luck, boys. Take care of the game for me.
Kyle: We will. Did you ever get his name?
Justin: No. What'd he give you?
Kyle: I don't know, but I think it's important. [Kyle holds a scrap of papers titled "The Playbook"]

Robin: [to Ted] Mr. Architect, big day for you tomorrow, huh?
Barney: Yeah, getting to stand next to me while I press the button. That is going to be legend... wait for it... dary adjacent. Legendary adjacent!

Barney: Yes! Tonight is going to be legen- Wait, are we sure it's a good idea to go to a strip club? Shut up, Lily!
I'm in charge now - dary!

Barney: Dude. Working together is gonna be legen... Wait for it. I'll send you an inter-office memo with the rest 'cause we freakin' work together!

Lily: So, there's this big gallery opening tonight.
Robin: Oh, we'd love to, but we've got this...
Barney: Genesis reunion, Madison Square Garden, front row. It's gonna be legend...
Lily: I wasn't inviting you guys.
Barney: Oh, thank God. There is no concert. [rips tickets]

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?!

Lily: Nothing good ever happens after 2:00 a.m.
Barney: You know, I have found, in my travels, that all the best things in life happen after 2:00 a.m. When I look back at the best stories of my life: the Liberty Bell incident, the little scrape I got in at the Russian Embassy, the almost four-way.
Marshall: You never had a four-way.
Barney: I said "almost." All those things happened after 2:00 a.m. because after 2:00 a.m. is when things get - audience, say it with me - legendary.

Ted: Why do you have those suitcases, and who are we picking up?
Barney: I don't know. Maybe her? Or her.
Ted: Wait, so when you said you were going to "Pick someone up at the airport". You meant you were going to "pick someone up" at the airport.
Barney: [winks] Scenario. Couple of girls fly into town, looking for a fun weekend in NYC when they meet two handsome international business men just back from a lucrative trip to Japan. Sample dialogue, "You have a wheelie bag? Wh- I have a wheelie bag!"
Ted: You've gotta be kidding me.
Barney: False. Sidebar, tuck in your shirt. You look sketchy.
Ted: I'm sketchy?
Barney: Trust me, it's going to be legendary.
Ted: Don't say "legendary", okay? You're too liberal with the word legendary.
[flashback:]
Barney: We're building an igloo in Central Park. It's gonna be legendary. Snow suit up!
