Marshall: Technically, I never lied...
[series of flashbacks of Lily phoning Marshall at work:]
Lily: Hey, baby.
Marshall: Hey, baby, I can't talk right now. I'm working on a big case. Bye. [to Bernard] That is a big case.
[flashback:]
Marshall: Bad time, Lily. I got to focus on the client. Gotta go. Bye. [hangs up] Where were we?
Bernard: Chapter 19.
[flashback:]
Marshall: I can't talk right now, I got a lot on my plate. [hangs up] Well, let's dig in. If we start now, we can be done by lunch.
[flashback:]
Marshall: Now's not a good time, Lil. We got a lot of balls in the air right now. [hangs up]
Bernard: Okay, toss me the stapler.
[present:]
Lily: Unbelievable. Wait, when you said you were about to get reamed...
Marshall: Oh, right. That. No, sometimes, for fun, We throw reams of paper at each other. [paper flies] Bernard! Not a good time! Read the room!
