How I Met Your Mother, Season 1

[Ted just told Natalie that he wants to break up with her...again]

Natalie:
[after throwing a handful of spaghetti at him] I'm NOT THE ONE FOR YOU!?

Ted:
I-I'm sorry. I thought that was the mature thing to do, I...

Natalie:
It's my birthday!

Ted:
Yes, I know it's just...

Natalie:
It's my birthday, and you're telling me I'm not the one for you?

Ted:
It's no big deal. It's not like you lost the lottery--

Natalie:
Oh, so dating you's like winning the lottery? [Ted stammers] So what's the problem?

Ted:
I can't explain.

Natalie:
Try!

Ted:
Well, it's just ineffable.

Natalie:
Oh, so I'm not 'F-able'?

Ted:
No, no, no, ineffable means it can't be explained.

Natalie:
So I'm stupid?

Ted:
What's going on?

Natalie:
What's going on is, you broke my heart over my answering machine on my birthday. Waited three years for me to get over you, tracked me down, begged me to go out with you again, only so you could dump me three years later, again on my birthday!

Ted:
No no, it's not like that...it's just...it's just-

Natalie:
WHAT!?

Ted:
I'm just like super busy right now.

Future Ted:
Remember when Natalie said...

Natalie:
[in flashback, at the bar] I got a Krav Maga class in about half an hour.

Future Ted:
It turns out that Krav Maga is not a form of yoga. It's a form of guerrilla street fighting developed by the Israeli Army.

[Natalie proceeds to beat up Ted]
