Quote from Robin in Spoiler Alert
Lily: Can you believe Ted? What a lame thing to say, that I'm a loud chewer. Robin: Yeah, that's crazy. Maybe enough with the pretzels. Lily: Oh, my God, do I really chew that loudly? Robin: No, no, no. Okay, now that you pointed it out, maybe it does sound slightly like someone put a screwdriver in a pencil sharpener, but in a cute way.
