I can tell you the time, all night long just by that Chinese restaurant. For instance... they start cooking the egg foo yung at 5:26. The first whiffs of that reach my apartment window upstairs at about, oh, 5:28. And they reach your window at about 5:27 and 56 seconds. It's a known fact that the aroma of egg foo yung rises at the rate of 320 feet per second. Now, moo goo gai pan, which is of a heavier consistency, travels upwards at a slower rate. They start making that at about 5:37. Sometimes somebody comes in, orders the family dinner, then I'm completely thrown. I don't ever know what time it is.
Ed telling Ralph how he can tell the time.
