How I Met Your Mother2005

Barney Stinson:
Watch your step when you get up kids, 'cause I'm about to drop some knowledge. Relationships are like a freeway.

Marshall Eriksen:
Wait a minute. A month ago you told me relationships were like a traveling circus.

Barney Stinson:
No, this is new, this trumps that. Freeways have exits, so do relationships. The first exit, my personal favorite, is six hours in. You meet, you talk, you have sex, you exit when she's in the shower.

Robin Scherbatsky:
So, every girl you have sex with feels the immediate need to shower? Actually yeah, I get that.

Barney Stinson:
[ignoring what Robin just said] The next exits are four days, three weeks, seven months - That's when you guys [pointing at Ted and Robin] are gonna break up, mark your calendars.

Ted Mosby:
Hey!

Robin Scherbatsky:
What?

Barney Stinson:
Then a year and a half, eighteen years, and the last exit: death, which, if you've been with the same woman for your entire life, it's like "Are we there yet?"
