Marshall: After we all finished talking last night, I went to the diner to finish working on the Ninja Report.
[flashback to Marshall at a diner working. Barney arrives out of nowhere and sits down at the same booth:]
Barney: Hey, Marshall.
Marshall: How long have you been sitting there?
Barney: If you go in there with Lily's kindergarten nonsense, you're gonna get torn apart. I'm here to save your life. You hungry?
Marshall: Yeah, I was just about to order.
Barney: What do you want?
Marshall: A sandwich and gravy fries.
Waiter: Okay, friends, what do you like?
Barney: A green tea with lemon for me, and for my friend here, the meatloaf, please.
Waiter: Very good.
Marshall: No, I didn't want meatloaf.
Barney: Marshall, the chain of screaming is a real thing. Arthur screamed at you, now you have to scream at someone else.
Marshall: No, I don't.
Barney: Yes, you do, or else that anger is gonna eat you alive.
Marshall: Who would I even scream at?
Barney: I don't know. How about somebody who's disappointed you? Someone who's let you down. Someone who's gonna bring you meatloaf when you explicitly ordered a sandwich and gravy fries.
Marshall: No.
