It's from the TV show - Friends ( The show is chic crack)
It's a play on the DHV story Joey gives to Ross to get women in the mood.
If you've not seen the episode * story here's the link:

So very early in the convo after a bit of fluff, I state that I like to watch the show Friends with my sister. Girls in the 20's, 30's will have grown up watching the show and will know every episode so plant the seed and start a new thread shortly after.

Later in rapport, comfort. (can be hours or days later). Into More serious talk, begin to say how you are passionate about traveling and lead into how you once traveled around Western Europe.

From here you should re-tell the story just as Joey does in the show.
Be completely serious, but as the point gets to where the story ends you should make eye contact with the girl and give a knowing smile, little smirk etc to see if she knows whats going on. If she does, then give her 'smart points' and tease her & laugh about it and say how into the story she was..

Post results. Performed correctly, this is a gem to use!!
