Rory: Can brains hurt?
Lorelai: Yes, it’s hypochondria hour.
Rory: No, I’m serious. Last night when I was reading my biology chapters I distinctly heard a ping in the vicinity of my brain.
Lorelai: Your brain pinged?
Rory: Yeah. It just went like “dink.”
Lorelai: Well then, honey, your brain dinked. It didn’t ping.
Rory: Well I don’t think a dinking brain is any less worrisome than a pinging brain.
Lorelai: Well, you got me there.
Rory: So should I go to a tumor doctor?
Lorelai: No, you don’t have a tumor. You’re reading too much. You’re probably just losing your eyesight.
Rory: Thank you.
Lorelai: You’re welcome.
