In this clip from the the upcoming episode of How I Met Your Mother, Robin and Ted are driving each other nuts as roommates. They think maybe have sex will solve the problem... much like Barney thinks it will solve world peace.
Ted: We should buy a bar. Barney: Of course, we should buy a bar! Ted: We should totally buy a bar. Barney: We should totally buy a bar. Our bar would be awesome. And dude, dude, dude, dude... the name of our bar... Puzzles. People will be, like, "Why is it called Puzzles?". That's the puzzle
Robin: Let's make a pact, if we both turn 40 and we're both single.. Ted: Robin Scherbatsky, will you be my backup wife? Robin: A girl always dreams of hearing those words. Yes, yes, a million times, yes!
