[flashback to Ted, Barney and Marshall in a booth in MacLaren's in 2001:]
Marshall: I'm not gonna cheat on my girlfriend.
[Lily walks in the bar]
Barney: Yes, you are, with the hottie that just walked in. Look at her. How much hotter is she than your girlfriend?
Marshall: There's no comparison. What do you think, Ted? Should I go for it?
Ted: Oh, don't do it, man. I mean, think about Lily.
Marshall: You know what, I don't care. I've been with one woman for too long. I need me some strange.
Barney: Yes, yes, pep talk. You can do this, but to be more accurate, you probably can't. You're way out of practice and she is way too hot for you. So, remember, tonight isn't about scoring, it's about believing that you can do it even though you probably can't. Go get him, tiger.
[Marshall gets up and heads over to the bar. Ted moves to the other side of the booth and sits next to Barney.]
Barney: Poor guy's gonna crash and burn.
[Marshall walks over to Lily and kisses her]
Barney: [spit take] That man is a god!
[present:]
Marshall: For like a week after, Barney followed me around, asking me to teach him how to live. I even got him to do my laundry once.
Barney: I thought it was a Mr. Miyagi kind of thing.
