See what I got going on here, they're turkeys but they're also hands. Because later we're going to eat turkey, and then I'm going to slap you in your face

Marshall

Robin: I'm sorry. Sometimes I forget how seriously you guys take American Thanksgiving. Real Thanksgiving happened over a month ago.

Ted: I mean, you got used to Lily's loud chewing, right?

[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?
