Ted, let me tell you a little story about a young lady I wanted ...
[Ted is discussing his girlfriend Cathy]
Barney: Ted, let me tell you a little story about a young lady I wanted to have sex with, Lucilia. On a white sand beach in Rio de Janiero, we made love for ten straight hours. When we were done, she applauded, and told me that I was far far better than the best lover she could possibly imagine, and that I had restored her faith in god.
Ted: What does this have to do with Cathy?
Barney: Who's Cathy?
