Quote from Marshall in False Positive
Lily: Marshall, I don't like this. Marshall: I know. Okay? I don't like it either. It's like I have a hot, burning ball of stress in my chest... and nothing will make it go away! [later, in a doctor's office:] Doctor: You're not pregnant. Marshall: Well, that did it. Doctor: I know this probably comes as quite a disappointment. Marshall: ... Yeah. Huge bummer. Lily: So disappointing.
