Quote from Kramer in The Engagement
Elaine: What time you got? Kramer: Oh, no. I don't wear a watch. Elaine: What do you do? Kramer: Well, I tell time by the sun. Elaine: How close do you get? Kramer: Well, I can guess within an hour. Elaine: [scoffs] Well, I can guess within the hour, and I don't even have to look at the sun. Kramer: Yeah. Elaine: Well, what about at night? What do you do then? Kramer: Well, night's tougher but it's only a couple of hours.
