Kirk: Oh, I can tell you what they're saying.
Lorelai: How?
Kirk: I read lips. My girlfriend taught me. It's so we can have quiet time and keep the conversation going at the same time. Okay, she just said, "Hardwood sponge is the authority of the hostile biographer." And then he responded, "Just phone cords to original samovars."
Lorelai: Kirk, that doesn't make any sense.
Kirk: Must mean they're on to us and they've switched to some sort of code.
Lorelai: I don't think they're speaking in code.
Kirk: Oh, I think Luke's heading back. He just got up and said, "Feel your taters."
Lorelai: Is it possible he said, "I'll see you later?"
Kirk: No, I'm pretty sure about this one.
