Marshall: Guys, I'm telling a life-altering story here!
[flashback to Barney and Marshall walking down the street:]
Barney: A 20% tip, really, for that waiter?
Marshall: I don't know, Barney, he worked a triple, it just...
Barney: I can't believe it! If you're not gonna yell at the waiter, Yell at me.
Marshall: What?
Barney: Yell at me.
Marshall: I'm not gonna yell at you, Barney.
Barney: What, you think you're gonna upset me? Please, give me your best shot.
Marshall: Okay, fine... what, you want me to yell at you?
Barney: Yeah.
Marshall: This is me yelling at you, Barney.
Barney: I'm sorry, I couldn't hear you over the sound of a butterfly landing on a leaf about three blocks away.
