Quote from Marshall in Pilot
Barney: So, Marshall. This "Olive Theory" based on you and Lily? Marshall: Yeah. Barney: You hate olives? Lily loves them, you can't stand them. Marshall: Yeah, hate olives. Barney: Two weeks ago, Spanish bar on 79th Street, dish of olives, you had some. What up? Marshall: You have to swear that this does not leave this cab. Barney: I swear. Ranjit: I swear. Marshall: On our first date, I ordered a Greek salad. Lily asked if she could have my olives. I said, "Sure... I hate olives." Barney: But you like olives! Marshall: Well, I was eighteen, okay? I was a virgin. Been waiting for my whole life for a pretty girl to want my olives.
