Penny: Are you sure you don't want to go to the emergency room?
Leonard: No, no, I'm okay, it's stopped bleeding.
Penny: I know, but you did throw up. Isn't that a sign of a concussion?
Leonard: Yes, but I get car sick too, so...
Leonard: Sorry about your car, by the way.
Penny: Oh, no, it's fine, you got most of it out the window.
Leonard: The poor guy on the bike.
